Dear Stefan,
Thanks for your response.
I'm using VDR 1.4.0-2, softdevice cvs 2006-5-30, nVidia 6200TC video card, nVidia binary driver 8762, Xorg 6.8.1, TV-out (NTSC) @ 800x600x24bpp, GCC 4.1.1 .
Newer nvidia cards do not support Overlay mode: http://lists.berlios.de/pipermail/softdevice-devel/2006q1/001770.html
Wow, I'm blown away by this. I had no idea nVidia would do something this dumb. The newer cards support XvMC, does this option help my situation out any:
'Option "XvmcUsesTextures" "boolean" Forces XvMC to use the 3D engine for XvMCPutSurface requests rather than the video overlay.' ? I guess it might if softdevice supports XvMC.
I noticed tearing during DVD playback using xine and mplayer, I guess it is also because there is no video overlay support in my card.
For OSD, if I use "psuedo", in full-screen mode, the entire OSD "blinks" when there is video and the OSD is not usable. If I use "software" for OSD setting, then OSD looks OK but when overlayed over video, OSD colors are all wrong.
Wrong OSD color only ? Or both video and OSD ?
The OSD color was messed up only when there was video (I was using the "dvd" plug-in for VDR). Without any video, the OSD colors look fine (either psuedo or software).
Use softdevice setup OSD and try to change the HUE value to max (100). If you can read german, have a look at this: http://www.vdr-portal.de/board/thread.php?threadid=49914&hilight=nvidia+...
No, I can't read German but I'll try this through a translation website.
I've seen similar behavior on a TNT2 using the opensource "nv" driver, and other bizarre problems using ATI cards (both opensource and ATI proprietary drive), so I think something in softdevice OSD code is incorrect.
Radeons (rv280:9200 and rv350:9550) work fine even with pseudo mode using Xorg 7.0 here. The limitation in pseudo mode is, that it is not a real alphablend mode.
I found with ATI, if the screen resolution was less than 800x600, than the OSD very messed up. That isn't a huge problem actually, but I just moved to a PCI-Express system and all my ATI cards are AGP :( .
Also, ATI does not seem to support XvMC. What is the status of XvMC support in softdevice?
Best regards, CR.

What's so dumb about that? The video blitter does about the same thing and more through the same old XVideo extension. Actually the blitter has much better scaling quality and is a lot faster than the overlay on my old Riva TNT 2. It also seems that the open source driver uses the blitter as the default XVideo adapter, and doesn't even offer overlay, at least on my card. AFAIK the only advantage the overlay has are brightness, contrast and hue controls, but I'd rather use the controls on my display anyway.
Video textures through OpenGL seem to be the way to go since that allows hardware alpha blending for OSD among other effects.
