I used this once to encode a AVI to VIDEO_TS and burned a UDF disk in toast 6.0 and it worked fine. Since then the files I have tried to encode haven't worked out at all. I made couple of DVDS with AVI files and the DVDS played with the audio a few seconds off and a couple of them were just audio. My process is as follows *Check that the AVI plays in QT with codecs installed *Open the AVI in FFmpegX and use the DVD w/mpeg2enc preset (This is what I used on the first file that worked, the others were done using the programs own encoder. What is the difference in the two?) *Let it process overnight or however long it takes. *Burn the VIDEO_TS folder onto a DVD using the Data: UDF something or other setting in toast. So...am I missing something in encoding, burning to fast, using crap media? If it matters I am on a Sawtooth G4 with a 800 MHz upgrade chip, 256mb RAM, and a Pioneer A107 8x burner and the disks were Mememorex (I know they suck but they were free with the burner)
