I need to do some experiments. would a PAL dvd be a viable option for your target hardware? that's 25 frames iirc. if you can playback a PAL dvd then you can avoid the fractional frame rate all together. cheers, pete nb: kmediafactory is a fine template based dvd creator. i use kaffeine to record DVB streams, projectX to demux, pxsup2dast to create subtitles, spumux and mplex to mux to an intermediate mpeg, then kmediafactory does the rest in a jiffy. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
