MPEG video trouble Radeon 64 MB DDR

[nick lidakis <nick.lidakis@verizon.net>]

System: Tyan Tiger 230 w/dual 1 GHZ P3
                  512Mb ram
                  3com NIc 3c590
                  Ensoniq 1371 soundcard
                   OS's  Debian woody, debian SID, win98 SE via moblie
rack HD swap


Problem: Newly purchased Radeon 64MB VIVO works with openGL with all 3
OS's. While trying to play any MPEG (DVD, mpeg1, mpeg2) using any client
(Videloan 0.2.03, latest xine, etc), video plays fine but when switching
desktops the last frame played still remains on all my desktops. When
minimising the video window, the last frame played still remains. If I
try to place another window on top if the video window, that window will
not be shown on top of the video window. The only way to stop this is
stop playing whatever dvd, mpeg file I'm watching. This happened with
XFreee 4.0.3 and with the current XFree 4.1.05 release. DVD playback is
fine under win98. DVD playback is aslo fine when i drop in and old
Matrox Millenium AGP 8Mb card. 2 weeks now with no response from Tyan
Inc.

Anybody out there with similiar mpeg/dvd playback problems???
