Hi

Thanks for the detailed problem report. I don't think this is a hardware problem, but an interaction problem between the graphics or audio subsystem and the media player. Some further questions to narrow down the issue:

1. If you disable the USB2HDMI audio output, or select another audio output, does the problem still occur?
2. If you play the video on the ATI screen, but still send the audio to the DisplayLink graphics adapter, does the same problem occur.
3. When it freezes, can you drag other windows to the DisplayLink USB display eg is it just the media player that has frozen up or the whole DisplayLink screen?

If I was a betting man, I would expect an ATI graphics driver update would fix this. Your current graphics drivers are from Mar 2006, which is 10 months BEFORE Vista was released.. They are going to be buggy on Vista, and DisplayLink software is probably exposing some of these bugs.

Annoyingly, Dell don't distribute a later ATI driver and forbid ATI from independently distributing one. However there does seem to be one that someone has created to work around this:

Hopefully updating to this driver version should help.
