The 100Hz thing is just a workaround to get enough data on the link so that the HDMI handshake will happen :P I'd try to make a modeline: $ gtf 720 576 50 # 720x576 @ 50.00 Hz (GTF) hsync: 29.65 kHz; pclk: 26.57 MHz Modeline "720x576_50.00" 26.57 720 736 808 896 576 577 580 593 -HSync +Vsync $ gtf 720 576 100 # 720x576 @ 100.00 Hz (GTF) hsync: 61.10 kHz; pclk: 58.66 MHz Modeline "720x576_100.00" 58.66 720 760 840 960 576 577 580 611 -HSync +Vsync (if these blow up your 50'' fullHD plasma, you're on your own - try them at your own risk!) I'd suspect VDR+xinelibout would not support this out of the box. You probably need to make a script or something to change resolutions when needed. Also, xinelibout might not like resolution switches on the fly. But if this is the case, it could probably be worked around by making xinelibout / X part a frontend (I believe this is possible and a very common setup anyways), and restarting it when needed. OTOH, I don't see much gain in doing the above compared to the deinterlacing in software and then scaling, apart from saving some CPU cycles. I'd doubt any external display could do a better job, though then again, I haven't had any experience with those modern (post-4:3 CRT era TV) displays =) - Ville -- -- Ville Aakko - ville.aakko@xxxxxxxxx _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
