But I've heard that only the closed source driver as capable of 50 Hz for PAL. I did't test myself the open source driver with that low frequency. I hope one day the Nouveau project could give us enough support for PAL on nVidia with adequate drivers. > I'm currently using a G450 with softdevice connected to a CRT TV and it > works pretty well most of the time with the odd flicker due to dodgy sync > every now and than. maybe you can convince the softdevice developers to give the patch a try:) > Using hardware to do the deinterlacing is _definitely_ the way forward, for displaying interlaced content it's always the best to use a display with native interlace capabilities. So nobody has to deinterlace at all. You just route the plain fields straight through to the hardware. > especially for CRT. (Not sure whether LCDs display an interlaced > streame "properly" or whether they try to interpolate somehow and refresh I've heard modern LCDs do a pretty good job interpreting a conventional PAL signal. At the expense of huge amount of signal processing circuitry. _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
