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

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.
