well said typingsux... kpg, TMPG will not re-encode any files... your files will still be mpeg1 video streamed, and the vob files that you will create with DVD Author will have vcd video quality... but they will be 100% compatible with mpeg2 standards... How is this possible??? Believe me, it is... It could take a while to explain why, and the post might get enormous, but if you are really curious about this, just ask for more info and i'll make a short explain in dvd-video layouts, basic dvd-video structures and mpeg2 streams this weekend... With TMPG DVD author you can even create chapters... BUT, you cannot put any subtitle in the vob files you create, and multi-sound is useless... However, for simple things like vcds-->dvd is great... Just a quick info: video size will be 352X288 (vcd mpeg1 resolution), but that shouldn't worry you. Mpeg2 IS NOT always 720X576... DvD-video files can be sized as 720X576 (high quality), 352X576 (medium quality), and 352X288 (low quality)... For best TV viewing, video resolution should be adjusted according to AVB (Average Video Bitrate)... So, 720X576 for AVB value from 4000kbits/sec to 8000kbits/sec, 352X576 for AVB from 2000kbits/sec to 4000kbits/sec, and 352X288 for AVB from 750kbits/sec to 2000kbits/sec... AVB values higher than 8000kbits/sec are practically useless, as there is not known devices that can display such excellent image detail for moving pictures... AVB values lower than 1777kbits/sec are not recommended for PC usage, and AVB values are not recommended for TV viewing... Anyway, i can write all day about these things... Hope i helped...
