HD-200 DTS issues

[taylormadearmy]

Hi All,

-------------------------------------------------------------------------
EDIT - changed title as now this problem also appears with the HD100 with the 20081222 0 beta. See Voidpt's post #22 for details
-------------------------------------------------------------------------

I have been trying to play some mkv files that play fine on my old and trusty HD-100 that are having issues on the shiny new HD-200.

My HD-200 (as the HD-100 was in tha past) is connected digitally via optical cable to my amp. Files that contain DTS audio have an issue where the audio seems to be cutting out every second or so on the HD-200 - where they play fine on the HD-100... I'm running the beta from the 19th Dec.

Anyone else successfully playing files that contain DTS?

Thanks!
T

I have experienced the exact same problem you are describing. Although I have had DTS 1536kbit/s that have worked, on the HD200. So not 100% sure what the pattern is.

Anyway. I made a 30sec MKV that illustrates the problem. Have uploaded and bug reported it to SageTV. We'll see what they say.

Could you possibly share that test file for me to play with?

Thanks for the feedback - do report back what support say!

Many Thanks

No problem. Sent you a PM with details.

@taylormadearmy
I will report back any progress.

I've noticed this too.

Is the optical connection any better than HDMI? I use the HDMI for video and audio into my receiver for all my devices and let that handle the sound, while it passes through the video to the TV.

I'm no audiophile so would not be best placed to answer this. I'd guess there is not likely to be any appreciable difference given the fact they are digital signals.

My amp does not accept HDMI so it is a moot point to for me...

I've got one hd200 connected with optical and the other HDMI and I can't tell any appreciable difference between them. They both sound great, but each has the issue with DTS audio. I think this is another firmware gremlin.

Got a reply from SageTV. They told me that they could not detect any audio 'clippings' in the sample I sent them. I have recorded an MP3 of the actual sound from my speakers so I am 100% sure they understand the problem I'm talking about.

I'm really sure they would have noticed the problem easy. If it was there. Meaning, their HD200 is somehow setup in a way that do not exibit the problem.

I have tried some things after their reply. Changed optical cable to a 'high-end' one. Played in Extender mode over network (tests until now was a USBstick). And some other small things. But nothing has had any effect. Problem still there.

A little more detailed info about my system. My HD200 is connected with optical cable & HDMI through my Yamaha RX-V2700 receiver. One interesting thing about this is that the V2700 have some 'blinking-moment' in the LCD display part that shows the audio mode (at same time as 'clippings'). It usually does that when changing audio mode. It shouldn't do it when playing normally. So it looks like it looses the handshake/decoding of the DTS stream, but then finds it again. Or something like that.

Well. haven't got more time at hand now. Will test more later.

Hi

I just wanted to add that I am also experiencing the exact same problem with DTS soundtracks. All previously played fine on the HD100.

If you find a resolution please let me know.

Thanks

Problem is still there in the latest beta 200812122 0.

Can I have a copy of your clips just to check we have exactly the same issue? I'll then submit a bug report to support. Have you pointed them at this thread so they can see there are a few people with the same issue?

Cheers

Sure. I sent you a PM with details. And yes, I did point out this thread to them, and said there were more than me with same symptoms.

When I get time again in a few days I will work through my MKV / DVD (VIDEO_TS) library that have DTS sound and try to find a pattern. Because I'm pretty sure I have DTS 1536kbit/s that do work. So it would be interesting to see if there are some pattern to which DTS audio tracks that give the problem.

And I did also try the 20081222 0 firmware this morning. Same problem on my sample MKV.

Well, I am not sure if it helps but I don't have nor had any issues with dts playback via optical.

I did a lot of testing early in the beta of the HD200 due to the AC3 issue but found that DTS was always good.

Could it be that the dts issue you are experiencing is related to the dts implementation in your AV receiver? Maybe some receivers with a particular chipset may exhibit the different behaviour.

That thought has crossed my mind too. So if other people who have this problem could list the kind of equipment that does the DTS decoding, it could help. It certainly is difficult for SageTV if they cannot replicate the behaviour. So if they have available some equipment that matches ours, it could help.

As told further up. I have a Yamaha RX-V2700. Don't have the firmware revision here. Get it later if relevant.

I will also, to double-check, put my HD100 to see that problem disappear. As it seems it should (by other accounts in this thread).

I have the problem with optical and HDMI, but your suggestion about the chipset in the receiver is an interesting one. I was thinking along the same lines last night. I have an older Pioneer receiver hooked to one of my HD200's and a Sony 720 receiver I just purchased hooked to the other. The Sony seems to not be affected to as great a degree as the Pioneer however both exhibit the issue. Both of my receivers are pretty low-end. I'm wondering if a more expensive receiver would be more fault tolerant of a corrupted DTS stream.

I don't have an HD200 to test this out on, but the problem sounds a lot like one I used to have on my HD100. I posted a "fix" for this (see link below), and while I have no idea if this process will help here, you might want to give it a shot:

Thanks for the tip! I'll try it tonight when I get home from work.

Hi

If it helps, both of my HD200's are connected to seperate high end Meridian Audio decoders, and they both exhibit the problem.

My DTS audio streams are typically misic DVD's. All of my music DVD's fail on the HD200. The Eagles Farewell Tour is one of the albums if anyone else has it to try.

I guess that is certainly possible. Maybe some receivers are worse at handling marginal things - for example jitter.

I'm using a Yamaha YSP-500. I notice voidpt is also using a Yamaha amp. What are you other guys who are seing this issue using?
