You do not have to convert SVCD files to Put them on DVD..If you do, it will Just ruin the Quality and take time and an extra step that isn"t needed.... Just use "DVDLab" it will Take your SVCD Files and Author them to DVD without re-encodeing the Video (It has to re-encode the audio to 48000hz) and it is quite easy..... If you want to Join the 2 SVCD/Mpeg2 files first you can use Tmpgenc..It has a Simple Mpeg joining feature if you go to "File" to "Mpeg Tools" to "Merge & Cut"....Cheers
