I've got a Toshiba SD220E. My daughter wants to play the stuff she has downloaded from the web, which is in .avi or .mpeg or .vcd format, but none of these plays on the DVD. Can anyone tell me what format I have to burn on the DVD to be able to play them. Conversley would it be better to burn CDs (the individual files are approximately 500-600Mb). Any suggestions would be appreciated.
