there is
ffmpeg/video/dv_pal.qt
try it?
Yeah, thanks for this tip which looks good, interesting and
promising ;)
I noticed also this preset, but didn't bench test it. Now, seemingly
".qt" tells me it means "quick-time" (not qt gui)

And interestingly, the short cam test with Sony TR2000 Hi8 PAL
connected via the A/D converter, the result also looks promising :)
