We have a pioneer dvr-ao8xla and i am using prodisc dvd-r's. The first time I play the movie it plays almost perfect until the last 10-15 mins where it will skip a few times. Each play after that it starts to skip sooner. The more times you play it the sooner it starts to skip until it eventually freezes or won't let you play the disc at all. I've tried it in 3 different dvd players and each result is the same. I've tried burning at 1x but that doesn't seem to solve the problem. They play perfectly fine in my computer no matter how many times you play them. What is going on?
