The problem: I can select and play an avi file in vlc, Nero showtime
or Creative Media Player. It plays fine. When it ends I select the
second part, or another, different avi file and try to play it.

Frame speed is reduced dramatically, leaving a jerky picture with the
sound out of sync. The only way I can play a second avi is to reboot.

Has anyone seen this, or can anyone point me at a cure? It's really,
really irritating....

ps I have tried with the very latest Nvidia files. No difference.

TIA...Pete

Try these:

At the very least, it will eliminate codecs as the source of the
problem, if it doesn't fix it completely.
