Re: [vdr] PCI fun (RGB/PAL over VGA at variable frame rate)
I found this to be useful for me, however I'm using [EMAIL PROTECTED] and not NTSC colour encoding. http://www.linuxis.us/linux/media/howto/linux-htpc/video_card_configuration.html Nice background information.

[vdr] Skystar II rev 2.8 + dvbscan
Hi, sorry if i am making offtopic here, but at least i will try, i am sure someone could help me here. I have Technisat Skystar 2 PCI , rev 2.8 . It works sucessfuly ,usind v4l + drivers provided on technistar website. However dvbscan utility from dvb-apps hg does not works for me. *dvbscan returns unable to initialize frontend* . What is important, that dvb-apps older version, 1.1.1 from tar.gz works for me. However there is scan utility (not dvbscan) which generates channels.conf in format not recognizable for VDR 1.6. Can someone point me to solution? THANKS IN ADVANCE! David ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Right - some nice info. But the vga-sync-fields patch now voids some statements. It's no longer true that softdecoders must sync to the graphics card. In our case it's the other way round. As it should be. The patch of course is for [EMAIL PROTECTED] though NTSC should also be possible. In the meantime I issued a few more releases of the vga-sync-fields patch. Version vga-sync-fields-0.0.7 together with xineliboutput Version 1.0.1 or newer and parameter setting xineliboutput.Advanced.LiveModeSync = 0 give very good results for both viewing recordings and Live-TV. The system is already productive here. I will describe the new setup in my next release. Cheers Thomas ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
