I'm not exactly a "qualified" video technician per se, and I don't possess too many "skills" in this area, but I think I can point out a few things to look into.

When putting a movie file on a CD, there are two ways you can go about it; you can copy movie files to CD, restricting its use to computers, or you can create a CD using the VCD standard, which is playable by computers and many DVD players.

VCDs use a specific video format, MPEG2 I think, at a specific resolution, so there's less room for freedom. You can get about 40-50 minutes of video on those, I think, and for a while (and still to a large degree) Chinese movies used VCDs instead of VHS tapes.

If you simply want to copy a file onto a CD, look into DivX compression (I think also known as MPEG-4 sort of, but not certain). I have a movie file on my computer 20 minutes long at good quality and I'm pretty sure the resolution is greater than 320x240 (I can't seem to find an exact measurement), and the file is about 57 MB in size.

I'm not sure, however, if there's a cost for the programs or codecs or whatever needed to encode DivX files. There should be VCD-making programs available on the internet, though.

That's about all I can help with. So if it's enough, no problem, if it isn't, sorry. =)
