no playback of recordings made post-Win7 install

Do you see the same problem when you insert the GB-PVR Flow Status filter in GraphEdit?

[johnsonx42]

Yes. I first tried playing the graph as saved by GB-PVR with the Flow Status filter still there - blank screen. Just now I tried re-adding the GB-PVR Flow Status back in to the graph, blank screen.

Have you got a small sample recording I could download? Just a minute or so recording will be fine.

I've only got DVB-T cards in my machine at the moment, which means H.264 here, so I cant make a .dvr-ms recording myself.

[johnsonx42]

it's about 12 MB... can I just e-mail it to you?

[sub]

Ok, I'll PM you my email address.

Thanks for the file. I was able to reproduce the problem here. Unfortunately there doesnt appear to be a simple cause. Its dying somewhere in the Directshow framework when allocating memory. I'll be able to fix it, but its not the 5 minute type fix I was hoping for. I'll have to come back to it when things are a bit quieter at work.

Thanks for looking into this. Going with the video decoder set to System Default is fine for now.

I just discovered though that I can't watch a recording in-progress, and the symptoms are exactly the same (blank screen, no audio, but the timeline appears normal, playback position moves, etc). I thought I could before upgrading to Win7, but I only switched to DVR-MS a week or so before that so maybe it just never came up. Is that normal for DVR-MS recording, or is it possible this is related somehow?

Here's part of the prvrx2.exe-native log for when I tried to play a recording-in-progress:

Doesn't seem to be anything interesting in the log, and the graph is created the same as with a completed recording. As I type this the program is finished recording and now plays fine.

Any thoughts?

I dont know, but you havnt changed user account the recording service runs as?

[johnsonx42]

no, still set to Local System. I did check 'Allow Service to Interact with Desktop', as until I did the the web server wouldn't load.

Sorry - I dont know. If I were you, I'd look at moving away from dvr-ms.
