I downloaded an mpg file and it plays fine using Windows Media Player but i want to burn it to DVD as I have done with other mpg files plenty of times.When I Use TMPGEnc DVD source creator to try to encode it TMPGEnc says the file only runs for 10 seconds.I know the file runs for 20 mins.Its about 48 megs.This has happened several times with various mpg and wmv files.Any suggestions would be greatly appreciated.
