Actually, no : here I can select 1, 2, 3, 4 or 5. 1 has a very low pixel resolution. 2 and 4 are greyscales images. 2 and 3 have a decent resolution. 4 and 5 have the best resolution. (but 4 being greyscale as I wrote before)
I guess then this is device-specific feature. ADVC-100 only allows full-blown NTSC/PAL format...
