Playback Video Freeze, Audio OK

[ConvertX Convert]

I'm a GB-PVR newbie. Quite impressed with the software, and hopefully only a few tweeks from being blissfully satisfied. Any suggestions for the following problem would be much appreciated: My first recording was a 0.5 hour DivX recording that played back nicely in WMP9. Second recording was a 0.5 hour Divx recording (identical settings as first recording) that played back nicely in WMP9 for 2-3 minutes until the video froze, but audio continued nicely. Each subsequent playback resulted in video freezing at precisely the same spot, but audio always OK. Third recording was a 0.5 hour MPEG-2 recording that also played back nicely for 2-3 minutes until video froze, but audio continued nicely. I was, however, able to stream the MPEG-2 file to a D-link DSM520 and view it on my TV in its entirety, and although it was somewhat choppy, there was no video freeze on the television. Any thoughts?

Sorry to say it, but I no longer actively support the PX-TV402U or any of the other GO7007SB based devices, so you'll probably find they have lots of strange quirky behaviour with GB-PVR. There are too few people using these devices to justify spending the time supporting them.

I havnt personally tested GB-PVR with any of these devices in at least a year.
