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.
Now the frame rate. I don't know what AVSynthesis is doing, whether it
will interpret FPS="30" as true 30fps, or as the actual NTSC frame rate
(30000/1001). The difference is small, about 0.1%, so you may actually
ignore it if AVS actually does exactly 30 fps.
OTOH, it would be nice if AVSynthesis could do true NTSC frame rate.
I'm discussing this issue with Jean-Pierre Lemoine, via email, and he
says that AVS is basically built around the idea of using integer frame
rate values.
He said he may release the next version with the ability to accept
fractional frame rates, but in that case A/V sync is not guaranteed.
But all hope is not lost. There are some frame interpolators out there
that might just be good enough to adjust from 30 to 30/1.001 fps and not
destroy the image quality. I need to do some experiments.
