Playback choppy & no sound in GB-PVR & WMP, but fine in Media Player Classic

When I record a show using GB-PVR, if I try to play it back in GB-PVR or if I try to play it back by opening the file in Windows Media Player, the video is very choppy/jumpy and I get absolutely no sound. However, if I try to play the same MPG file in Media Player Classic, it works just fine.

Now, this seems to not be a problem with GB-PVR, but with my computer itself - When I record video in the Hauppauge WinTV 2000 software, it plays back just fine in the WinTV 2000 program and in Media Player Classic, but is similarly choppy & without sound when I try to play the files in Windows Media Player.

I have a Hauppauge WinTV-PVR 150 running on an Athlon XP-M 2200 in a computer using the nForce2 chipset (and the built-in GeForce4MX graphics chipset). I don't know if this is relevant, but watching DVDs works just fine in GB-PVR, and I have never run into problems like this playing files in Windows Media Player before (whether they are mpeg2, avi, xvid, divx, matroska, etc.)

I have tried changing the software decoder settings, but it hasn't solved the recording playback problems. I tried replacing my DirectX 9.0c quartz.dll file with the 9.0b one (as suggested in the stickied thread in the support forum), but that also had no effect.

I've searched through the forums, but haven't found any solutions yet. Does anyone have an idea of what could be causing this problem?

Well, I solved this problem, but created a new one.

First, I just want to add a bit of detail to what I said before. When I tried to open the files in WMP, there would be no sound, the video would be choppy for about 20 seconds, and then the video would finally just quit working. My CPU usage would shoot to 100% and remain there until I killed the process (whether it was WMP or GB-PVR).

I was able to look at the properties for the file, and saw that it was using the Cyberlink codec/decoder to play the video in WMP. I uninstalled the Cyberlink DVD player on my computer, rebooted, and now the video works just fine (defaulting to the InterVideo Non-DeCSS Decoder for Hauppauge). So I can now play back my GB-PVR recordings in both GB-PVR and WMP...

But I can't watch DVDs. This is kind of frustrating since this is a legitimate copy of Cyberlink DVD Player that came with my drive. I guess I'll figure something out though. If anyone has any suggestions, I'd appreciate them.

Find a copy of gspot. Its Here Use this tool to render the AVI or Mpeg. It will give you an idea of what is going on with your codecs. Could be that you have installed a "codec pack" at some time and it screwed up. gspot will render and play the file in a mini window
