Possible to adjust audio sync on HD100 extender?

[popechild]

My source (Dish) has a pretty bad audio sync problem on every HD channel (which is all I'm getting from them). I'm able on the server to use filter settings (in ac3filter) to adjust the sync so that I get in-sync playback. (This is for all of my HD PVR recordings.)

Changing the filter config doesn't appear to make a difference on the HD100 playback of the same files however. Is there any way for me to adjust sync on the HD100 to compensate for my bad source? I was thinking the HD100 was so much better for hassle-free playback that I was about to buy another one to use in place of my server, but this might throw a big wrench in things.

Any suggestions?

Or barring a software solution, is anyone familiar with an external product that would enable me to adjust sync between the Dish box and the HD PVR so I wouldn't need to adjust the sync on the server or HD100? Keep in mind that the audio is already trailing the video, so I'd need some sort of "negative" sync setting capability. Preferably something that supports optical, for whenever Hauppauge gets the 5.1 working properly...

Have you played with the Audio settings in the Dish Receiver? It has two settings for delay, and you may be set for the wrong one.

Long shot, but I figured it might be worth checking.

Pretty sure I'm familiar with what you're referring to (some kind of "HD" setting for the audio?), but I'm also pretty sure the 211 (non-DVR) I have doesn't have that setting. Please correct me if I'm wrong.

I'm not aware of a audio sync setting in the HD100, but your TV might have one (mine do). Doesn't help if running audio through a audio receiver, but if running straight from HD100, should help.

I have the same setup, Dish 211 --> HD PVR, with the audio way late. Can you share what you have set in AC3Filter?

I did notice that overlay with Arcsoft video and audio, the audio sync is the least amount late. Overlay is also helping with stutter.

Running through a receiver that has an audio adjustment, but not enough. Also, since OTA is in sync, even if I could adjust the Dish stuff properly, it'd throw the OTA stuff way out. I really either need for the HD100 to be able to use the sync settings that the server is using, or I need to find a way to adjust the sync on the HD PVR material before it's ever actually saved (or at least before it's ever played back).

I have the AC3Filter sync adjusted by -180ms and it looks pretty good on the server. In terms of Arcsoft vs. others, I don't see that it particularly makes a difference in this case unless it actually affects sync on the HD100, which I'm not seeing. I don't have a problem with sync on the server since making the AC3filter adjustment.

I tried to watch the CNN political forum Saturday night, and it's like watching a dubbed ninja movie. I'm just hoping somewhere along the way, someone's figured out a way to "correct" an out-of-sync source for HD100 playback.

Just wanted to throw a "Me Too" into the thread.

I have a slight audio delay as well when using my HD-PVR in conjunction with my SA8300HD cable box. The amount of delay is equal using the Sage client on the Sage server or through an HD100 extender. The delay is also not as pronounced when using the ArcSoft software.

If anyone can provide a means to adjust the sync on just my HD-PVR tuner I would be extremely grateful

Thanks
Bill

Got the Dish 211 changing channels yesterday by installing a USB UIRT. So I tried the H.264 channels through the HD PVR, playing on the client and audio sync was spot on. The same channels on the server are very out of sync.

Will try the Media Extender tonight. (Edit Media extender out of sync with lastest firmware and 6.4.7 server)

Have you upgraded to the lasted Sage 6.4 and the newest HD-100 firmware? I haven't had sync problems after I did that

You may not have been replying to me, but my issue is that the source itself is out of sync, and I'm trying to figure out if there's any way I can "fix it" for playback on the HD100.

My source plays fine to the TV, Server (EDIT and Media extender) has audio sync problem but Client does not.

Okay, much testing (and one very annoyed wife) later, and I've found out some interesting stuff on this audio sync thing. As with so many situations where debugging seems to take longer than it should, it turns out there are a handful of "other" issues that have made it harder to get to the bottom of it...

1) Some dish channels are definitely out of sync, at least somewhat.
2) My receiver in the basement (where my only dish box was located) apparently has a slight sync problem of its own.

So it was looking like the problem was 100% with Dish b/c of the av receiver problem, but I moved the Dish box to a different tv where I could listen through the tv speakers, and the direct output from the dish box is pretty much in sync. There are a few channels that are a little off, but not too distracting.

So I know there's something going on besides an output problem. Since my server uses the same basement receiver that has the sync problem, and it's not easily moved, I installed Sage on a separate laptop machine. Installed the HD PVR as the only source.
- Test sync using Arcsoft player = check
- Test sync w/in Sage = check

Now I go to the HD100, and point it at the new laptop installation as the server. It finds it, I go to the exact same program I was just watching...

Out of sync pretty noticeably.

I can go back and forth between watching on the laptop and watching on the HD100 being served by the laptop, and the sync is definitely off on the HD100 compared to the server playback. It took me this long to notice the discrepancy because until now I'd been using a server that ran through an av receiver with its own sync problem, and I just assumed it was the same sync problem - which made me assume it was the Dish box.

BTW, I'm using the latest HD100 firmware and 4.6.8 server software.

I haven't noticed a sync problem on my OTA sources, other than maybe very slightly here and there. But off the top of my head that could either be because there's enough of a sync issue on the Dish source that it becomes noticeable when compounded with the HD100 sync problem, OR the HD100 could be having sync problems playing back the AAC audio from the HD PVR files that it doesn't have when playing back OTA HD files.

I saved a small clip from the program I clearly noticed the discrepancy on, and will try to convert it to a different format to see if that makes a difference when playing back on the HD100.

I will be setting up a R5000, so then I can compare the audio sync between HD-PVR and R5000.

At this point I am thinking the audio sync mismatch is a problem with Sage's interface with the HD-PVR.

Anyone find an audio sync setting in the VIP211 box? (EDIT, if there is an audio sync setting on the receiver, I can't find it)

Thanks, this is a great workaround for the sync problem. I just switch to AC3Filter on the problem source.

Thanks again

I'm very interested to hear your review/comparison. Do you use an extender? I'm contemplating which way to go, r5000 or hdpvr.

I have one HD-PVR and one R5000-HD both from VIP211K and VIP211 receivers, but the rack is being reassembled, so it will be a couple of days before I can check their outputs to the HD-100.

I needed the HD-PVR to capture the CC data on screen, but prefer the idea of capturing the original digital file with the R5000. I will be looking into trying to get the CC data from the original H.264 files.

OK, here are the results of side by side comparison of a HD-PVR and a R5000-HD to a HD-100.

HD-100
on HD-PVR
STB outputting 1080i - Bad audio sync problem, crawler on CNN is fine.
STB outputting 720p - Stutter on CNN crawler (Everything else too), Audio in sync.

on R5000-HD
No stutter or Audio sync problems at all. Slightly slower channel change.

I will keep the HD-PVR until CC data can be extracted from the H.264 channels, after that I would prefer just using R5000-HD units even at a higher cost.

Note - I installed the R5000-HD unit as a separate box external of the STB for portablity. I wanted the flexiblity to move the R5000-HD between multiple STB's easily.

I'm also having an audio sync problem, only with HD recordings. I hadn't noticed until a recent episode of This Old House - hammering nails is a good test for sync, and this failed.

Interestingly I had a SD recording of the same show, and the sync was fine.

I played the HD file on a computer, it sync was fine. So it seems to be an issue with the extender itself, no? This is Sage 6.4.8.184, and the 20080812 firmware.

I have found this too, seems I get a slight glitch in the video and then my audio goes out of sync, but....if i stop the video and then start it again ( same point ) the audio is back in sync.
