After transferring TiVo recordings to my computer, I'm having trouble burning them to DVDs. I believe the format is tivofile. A message says something about the file being larger than 2GB and therefore cant be stored in an ISO file system. It also mentions putting it in UDF format. I burned something as a UDF but it wont play in my DVD player. Any suggestions on how I can burn a tivofile onto a DVD? Thanks in advance.
