[mythtv-users] Frontend crash when skipping through video

I'm running Archlinux 0.8-2 which has MythTV in binary form at version 0.20.2.20070828-2. I can fast forward through video at 2x and 3x, but when it gets up to 5x or more it hemorrhages and dies. The same goes if I try to skip through using the arrow buttons repeatedly. This occurs for both LiveTV and recordings. I'm running the official nvidia drivers with an Nvidia 6600GT Pcie. For capture cards I've got two Leadtek Winfast DTV 1000t's (cx88). Here's the console output of mythfrontend.

This seems to be the crux of the problem. Then it devlolves into printing:

2007-12-10 04:48:43.237 NVP::AddAudioData():p1: Audio buffer overflow, audio data lost!

Endlessly until everything catches up. Depending on how far or radically I've tried to skip around in the video, this can either be a few seconds or I'll have to kill mythfrontend as it stops responding entirely. Any help would be appreciated.
