Jerky Ripped DVD Playback with Subtitles

[MichaelColey]

I've ripped several dozen DVDs from my DVD collection onto my 500GB hard drive for more convenient playback through the GB-PVR Video Library. When I turn on subtitles on any of them, the playback becomes jerky.

What can I do to improve the performance?

What video renderer and decoder are you using? Does Overlay work any better?

[MichaelColey]

Video Renderer: VMR9

Video Decoder: System Default

I haven't tried the Overlay Manager, but will give that a shot.

How do I tell what the "System Default" video decoder is? The only other option is "Nero Video Decoder".

I'll experiment a bit and see if any other combination of options works better.

Video Renderer: VMR9

Video Decoder: System Default

Its best to explicitly select the decoder, rather than relying on a random one directshow chooses.

How do I tell what the "System Default" video decoder is? The only other option is "Nero Video Decoder".

Its probably the Nero one, but you can double check by reproducing the problem, then looking at the filter list in the gbpvr.exe-native.log.

I dont have first hand experience with the nero decoder, but from what I've read its a bit flakey. Most people use the Cyberlink or Nvidia decoders for DVD playback.

I switched to the Cyberlink Video Decoder, and it does the same thing.

I tested all of the Video Renderer options, and they're all worse:

With VMR9, the video is jerky.
With Overlay, I just get a black screen when I try to play a DVD.
With VMR7, I lose all control. I can't FF, or navigate DVD menus.
With VMR9 Custom, GBPVR totally locks up.
With VMR9 Fullscreen Exclusive, I get a black screen when I try to play a DVD.

Nothing springs to mind, but zip and attach the logs and I'll take a look.

I've got a large collection of DVDs ripped to the hard drive. Playback of these works well for me.

[MichaelColey]

Normal playback works fine. It's just when I turn on subtitles (and when they're actually displayed) that it's jerky. It took me a while to figure that out.

I've looked through the logs and didn't see anything that jumped out to me. I'll send some over, though.

[MichaelColey]

Here are the logs.

Sorry, I cant really see anything obvious in there. It all looks ok.

Just wanted to add that I experience the same condition (jerky video w/ subtitles) as Michael on my Dell SC430. In my case this is not a GBPVR issue because the problem occurs in Windows Media Player as well. I gave up trying to figure it out I know this is not much help to you in correcting your issue but just wanted to add my 2cents
