Video and Audio not Syncing

[mas0nite]

This is a great program, but my problem is that the video starts to slow down after watching it for more than 15 mintues. This means that I hear the audio slightly before the video happens. This happens when I use LiveTV and when I use LiveTV with timeshifting. I have 2 tuners set up pvr150 and pvr250. Any Ideas on how to fix this?

Change the playback decoder on the playback tab of config.
Try different ones.
Download the latest one from hauppauge.

Another thing you can try is to keep your hard drive defragmented. I defrag mine every 24 hours, and that seems to have helped, at least to a great extent.

Ive tried several decoders and I am getting the same problem with most of them. Usually happens if I start the OSD but changing channel will do it too.
