I recently got a Memorex bluray player. Since we first got it about a week or two ago, it has issues with dvd's I've burned. It plays regular DVD's that you buy or rent just fine. But burned dvd's after a certain amount of time. I'd say about half way or a little more into the move it will start like freezing...and play...freezing and play continuously. I've tried stopping it and starting it again, but it keeps doing the same thing when I re-start it. Now it says it plays DVD-R's and +R's. I'm using -R's because my old DVD player had a problem with any other disk other than that or a regular DVD. I've played these burned moves on many other DVD players just fine. It's only since we got the new bluray player that they are having this issue. Is this a defect in the bluray player and we should exchange it for a new one, or is it a setting we have to switch in setup? Is this normal and most players have issues with burned DVD's because it's a blue ray player? Just wondering. I'm new to bluray. Thanks
