:: goes by tracklength (mode2) rather than filesize (mode1) so yes, they will fit fine. -pHo
um... actually, pho, it goes by space the same as mode 1 does; ppl are just used to saying 'it goes by length' when talking about vcd, since vcd is CBR & therefore the same length will always have the same size. obviously, with vbr, higher bitrate = bigger file = less track time you can fit onto one disc, so it's still going by size, not length.
the reason is sector size. normal data discs store fewer bytes per sector, because there is a part of every sector reserved for crc information (for error checking), the idea being that it's a lot less critical for a movie to have a couple of single-bit errors, than for an application (for instance) to have them, since one wrong piece of information can render a program inoperable, whereas you probably won't even notice on a movie, unless there are a lot of them. so, a 700meg / 80 min cd actually holds more than 800 megs of data... it's just that when writing a normal data disc, a chunk of it is used up writing redundant information.
