Sorry for the delay. Herbert Valerio Riedel has this to comment: well... there's a general issue with sector addressing; it's a limitation in the format: sectors aren't represented by simple (linear) 32bit values in the vcd structs and the cdrom sector headers, but instead msf-style bcd-coding is used, leading to an upper limit of ~450k sectors (== 100 minutes) the other issue is, that vcd's use cdrom mode2form2 sectors, which are able to carry 2324bytes of payload together with a few bytes of subheader; but afaik the DVD media allows only for 2048 byte payload/sector without any provision for subheaders... so it simply makes no sense to write a vcd image to dvd media.... one should really just use the dvd-v format for video-carrying dvd's... dvd players already have a hard time recognizing vcd's on CD-R's...
