i think the "tried to upload empty file" message means the connection timed out before you could finish uploading the file. you will need more upload bandwidth to finish the upload. also, there's currently a 100 meg file limit, so make sure not to go above that with one file.

yes, basically divide 59.94 (or pal 50) by whatever the number after the f is. afaik that shorthand was invented by me to help me talk about quality settings quickly, but it can of course also be applied to the original material (virtually all 3d console games except some of those on the gamecube are in fact f2, giving them their "dreamy" feel when played). also see here for more info (though i don't think i'd invented the shorthand yet at the time i wrote that).
