How I stopped VMR9 stuttering (including 1080i) and solved all my sound issues.

Turn off service mode before you make and save the change. Then turn service mode back on.

Thanks, Dave

Oh okay, I don't have it in front of me, I was just assuming that if the sage.properties files doesn't affect the behavior then it must have an equivalent entry in the sageclient.properties file. It's generally true but obviously not in this case.

Sounds like Goodspike knows what he's talking about and not me.

I don't think the setting would be in the sageclient.properties file because the client doesn't do any recording and therefore wouldn't control a recording's file type.

That is correct.

Hi,

Update: I have upgraded my second client to V6. I have tested HD and have had no troubles so far.

Sorry. It looks like I will be no help in resolving this issue.

Ok,
I tried every combo I can think of. Service off, Sage Shut down and verified Sage Properties file reads (mmc/encode_digital_tv_as_program_stream=true)
I get PS files when recording digital OTA off of my Divco lite but the HDHR always records TS files from both tuners set To QAM.
To be honest it does not seem to be a problem because I get virtualy studder free playback from both digital SD & HD QAM recordings, but I am just curious why Narflex posted that Sage no longer supports TS files. Maybe the HDHR latest firmware update has something to do with it.
Oh I am using Sage vr 6.1.4RC. Not sure I want to install the 6.1.6RC yet.

UPDATE
I think I found the answer in a post by Narflex.
Basicaly he said that this (mmc/encode_digital_tv_as_program_stream=true) only applies to local devices and not network encoders like the HDHR. He also said that Sage does still support TS file playback from other non local sources like the HDHR. I am not sure you can even get the HDHR to capture anything other than TS files. Maybe someone else can confirm this.

My HDHR is currently recording PS. All I did was change the mmc/encode_digital_tv_as_program_stream setting to true.

To confirm I just did a quick test:
mmc/encode_digital_tv_as_program_stream=false = TS from my HDHR
mmc/encode_digital_tv_as_program_stream=true = PS from my HDHR

This is with 6.0.x not 6.1.x.

Out of curiousity? Does anyone out there have a stutter-free configuration *not* using FSE? I'm still not a fan of FSE, but that is the only way I, too, *almost* get stutter-free HD I plan to try the latest 6.1.x RC later this week to see if I notice any difference. PC specs are below.

I wouldn't think so, since nothing has yet been resolved. Once it is, then certainly a candidate for a sticky.

I'm leaving original post below for information, but after further experimentation I can not consistently recreate stutter or smooth playback for HDTV, doesn't seem to matter if I record as .ts or .mpg, use FSE or not. very weird....I have a clean install that I image using Acronis just before installing:

SageTV
nvidia decoder

so I should be able to do pretty good a-b comparisons...

-------------------------------------------------------------
I'm currently going through this as well, here is what I've found:

using hauppauge HVR-1600
FSE with VMR9
- no real difference. Having friends watch who do not know I'm changing the setting, they can not tell a difference. I feel it is slightly better in FSE though.

Turning off VMR9 mode and going to overlay seems to take care of the issue.

Using graph program (which is pretty good program), it is going from file to Sage to split audio/video, then through nvidia decoders (no ac3 filter)
I believe this program is just showing default settings and sage's settings would override it if different, but it is good program to try different decoders and watch frame rates. Interesting enough, i could not get any visible stutter using this, but could see differences in frame rate and the jitter parameter (around 1-2), but it played much better than in sage, which I don't understand why (Sage is all set to defaults for decoders)

Changing to recording in .ts made nvidia split the audio/video in graph program and had better frame rate and jitter at 0. Stuttering is also gone in sage. FSE mode now definitly has no effect. I'm not sure why I can't get nivida to also split audio/video for .mpg, but I'm working on that. Will probably not install/uninstall sage decoder and see what is used to split audio/video.

Does anyone know how nvidia post processing is supposed to work, if I select that Sage closes...

hopes this helps...

Sorry, your observations are not correct. The file extensions may be changing; but the actual content in the file is always TS if it's coming from a HDHR network encoder.

TS files start with 0x47 as the first byte (and every 188th byte after it) and for PS it'll start with 0x000001BA for the first 4 bytes. That's the definitive way to tell.

I verified that the first byte is 0x47 for all files coming from my HDHR.

Why does SageTv change the file extension when the actual file type does not change?

Thanks for the information.

Golly,

Just wanted you to know this solved all of my SD stuttering issues and I was able to get the sound working properly through SPDIF.

Thanks for documenting this for us.

I think this thread should be made a sticky as it solves a good majority of stuttering and sound issues for a lot of folks.

THanks again.

You're welcome. It's great to hear this working for people. I do plan on testing whether setting the Nvidia demux is actually needed. After reading what Narflex had to say my guess is that Sage Demuxer + Nvidia video decoder + AC3Filter Audio decoder (which Narflex says is what Sage would be doing in this situation anyway) is all that's needed for smooth VMR9 playback.

My HD playback is smooth as silk in VMR9 with FSE turned off. My source is an HDHR running the latest non-beta software/firmware. I have a headless server and my client has an Athlon64 X2 4400+, 1Gb RAM, and an Nvidia 6600GT (pcie) video card running at 1080p. My software configuration is SageTV 6.0.18, JRE 1.6.0, Purevideo decoder (.223), and Forceware driver v84.21. (I saw a huge PQ improvement reverting to this driver version) I haven't tried upgrading to SageTV 6.1 yet.

Strangely, I have occasional problems with SD playback stuttering but not HD. I think it is deinterlacing related and I can get it to go away by hitting skip fwd or back once or twice.

Aloha,
Mike

It may be that the 84.xx driver is the key to your success; unfortunately that driver doesn't support the newer cards that many are using.

I have learned some things (still working), as mentioned before, in the nvidia decoder interlace modes, automatic, smart, and video all use 60 frames per second using fraps and film makes it 30 frames per second. I have found that 1080i seems to be most troublesome and have been concentrating on 1 clip. I have found that shows with scrolling bars or credits are very good at assessing stutter. using nvidia video and audio, i get pretty bad stutter in automatic, smart, and video. Setting to film helps, which makes sense send 1080i broadcast are at 30 fps. Interesting enough, if I change to the AC3 decoder it is much better. So, my settings from worse to best:


nividia audio and video decoders, interlace set to automatic, smart, or video
jumpy playback

nvidia audio and video decoders, interlace set to film
somewhat better

nividia video and ac3 audio, any interlace setting
best so far

in WMP playback is smooth no matter what the above settings are...
