Lol, you dont need to burn svcd/vcd files on to a cd..........you can extract the core avi file using something like isobuster, and then burn the resulting MPEG/MPEG2/MPEG4 file on to a dvd.......
And if your using NERO, open nero burning rom, then when it says " new compilation " select DVD-Rom (iso) then right click the window and add teh files....Along the bottom will be the standard slide bar showing how much of the dvd space is being filled by your file.....Then burn as normal.
All this will be a waste of a disc though if your dvd player wont play non compliant dvd discs.....
