If a video's good, i don't mind waiting to download it before i watch it.
If it's a minute long, i don't mind waiting 2 minutes to download it.
Going by that, i'd happily download your video if it's 50MB.
Most people are on half meg connections (56k-ers shouldn't be downloading videos, and if they do, they shouldn't complain about file sizes) so your video shouldn't be any larger than 7MB.
