I had a 1 1/2 hr project. I used IMoive 5. I changed the settings to good On IDVD so that it let me put the movie on 1 DVD. I burned the DVD-R and it viewed OK on the computer but did not on my DVD Player on my TV. I was able to view other projects that I have done but they were never longer than 1hr. Any reason why I couldn't view it?
