First off I have been burning .avi files to data dvd's without problems for a long time. My Dvd player is a Philips DVD5982, also very old. It works well with all my old files and even plays most new ones. I say most b/c that is where the problem is. It will just freeze on some new files, and go back to load screen. I have tried buying new dvd and blu-ray but that just caused more problems. The Philips tech suggested 1. cleaning it with a disk cleaner 2. burning at slower speed 3. that my reader was gone. 4. that it was a code issue. I tried and troubleshooted all, nothing seems to work. It can not be the reader or it would not play at all especially old ones. It can not be the specific new files, b/c they and the disk work just fine on the pc, all the way through. If it were the codec issue, why would it play at all. Below are 4 movie specs. The top 2 failed after 3/4 of the movie. The last 2 played all the way through.
