Stefan & everyone else ,
This weekend I spent time and completely un-installed my Xorg, and compiled modular Xorg 7.1 from sources. I also fetched vdr 1.4.1, and softdevice 0.2.3a, dvd-cvs and compiled them, no other plug-ins, ZERO patches to vdr or softdevice.
I setup Xorg to use the "nv" driver (opensource) and found the overlay issues still persisted. This is with 5-6-5 color depth, 640x480.
I then installed the newest nVidia driver, 1.0-8774, with color depth of 24bpp (32bpp), 1024x768 had the same issue.
Interestingly, before I start the DVD plug-in the overlay is fine. During DVD playback the overlay has the issues I have mentioned before. But oddly, *AFTER* DVD playing is completely stopped, the overlay remains messed up. i.e., the OSD with no video in the background, telling me "invalid channel" has the artifacts.
Does softdevice grab a black background image or something along those lines when video playback is first initiated and keep that for the OSD?
CR.
