GBPVR Recordings Jerky - WinTV2000 Recordings Perfect

[Eoghan]

Hi everyone,

I was wondering if anybody had had the same experience I have had and if anybody could help me.

I've been using GBPVR for a couple of years now and I love it.

I've been using it with a Hauppauge Win TV PVR 350. I had lots of problems setting it up and it's a great card. Now, before you all roll your eyes, the problem isn't with this card. I know this card has caused many people heartache, and sub no longer supports it. However, once you do get it working it's excellent. Anyway...

My issue is with a Hauppauge WinTV Nova S Plus which I added recently.

Everything is working fine, but Live TV / Recordings are very jerky. Specifically, the audio is fine, but the video starts to lag and jitter, and it gets further and further out of sync. I'm not too bothered about live TV, but would like to get recording working properly.

I am using the TV out on the 350 to play it, but it's also the same if I don't use the 350 TV Out so I don't believe the 350 has anything to do with it but I'm open to correction.

The jerkiness is in the recorded file itself, it's not just happening when I play it back. If I play the file on my PC monitor (even not through GBPVR), it jerks in exactly the same places.

What I've discovered is that if I record a file in WinTV2000 (the Hauppauge application), the recording is perfect. And it records directly to MPEG, which is what I'd like to do in GBPVR, as then I can play it over the 350 TV Out, and I don't need to do any post recording processing. Also, both my test recordings (GBPVR and WinTV2000) were to the same drive at different times so it's not that. Also the 350 records fine to that drive. Right now by the way I haven't got the 350 even set up in GBPVR so they're not both accessing the drive or anything.

I don't know a lot about this, but I'm guessing that perhaps WinTV2000 must be using a mux, and that mux is better for the card than any other, and also that mux is recording straight to MPEG, which is what I want. I've tried the DVR MS mux under the BDA Multiplexer list on the Misc tab in config, and it's not as jerky as the cyberlink one, but still very jerky. Also it doesn't produce MPEG files, so post recording conversion is necessary which is something I'd rather avoid as I know it's highly experimental right now and hogs my system CPU to 100%. Right now I'm not doing anything special - this is plain vanilla recording.

So does anybody know what mux WinTV2000 is using and how I can get GBPVR to use it? I think that might solve the issue. Maybe I'm on the wrong track. Any ideas anybody?

I'm using 1.0.8.

I've gone through a lot so far to get this card working (the quartz problem, needed new files from MCE for tuning, and loads of other issues), but I'm stuck on this one. If anybody could help me I'd really really appreciate it.

Thanks,
Eoghan.

Yeah, it is most likely the mux causing your problem.

Can you run muxchecker, then post the output?

The Hauppauge mux cant be used in external apps. It just crashes if you try. Its hard coded to only work with the other Hauppauge components.

Hi sub,

thanks for the reply.

Here's the output from Mux Checker.

---

GB-PVR has detected the following multiplex filters on your machine:

Found: InterVideo Multiplexer
FILE: c:\windows\system32\intervideoimux_3.0.88.0_.ax
VERSION: 3.0.88.0

Found: PP MPEG Muxer (aka, CyberLink MPEG Muxer)
FILE: c:\windows\system32\cyberlink_ppMpgMux_5.0.0.3608_.ax
VERSION: 5.0.3608



If you're running WinXP SP1 or higher, you will also be able to use the built-in DVR-MS mux filter

Have I got a setting wrong then or something that I can't use the Cyberlink one properly? Or is my PC too slow? P4 2.8GHz 256MB RAM

Thanks,

I'd try the Cyberlink v5.0.1307 mux. I use this particular one, and my recordings are very smooth.

It might also be worth setting <BDADisableStatusChecks>true</BDADisableStatusChecks> in the config.xml. Some users have found these status checks can cause small jerks with some devices.

sub,

you're a genius. 5.0.1307 did it. Downloaded MediaPortal (saw another post that said it contained it) and after that GBPVR worked great.

On live TV I do get some tiny jerks, but not much. I might still try your second suggestion. But I'm happy now.

Thanks ever so much.

Eoghan.

Cool

Anyone know the filename for the Cyberlink MUX?

EDIT: NM, I found it. MpgMux.ax
