None of my DVD-R's work in my portable DVD player (Panasonic LV75) although they should do. I even have a friend with the same player and his will play my discs. I am using Nero 6 and there are so many options to do with ISO etc. that I'm wondering whether tweaking some of these may solve the problem. Is there a most compatible set of options that I can choose ? I currently just use the DVD-Video template and accept all defaults. Works fine for all standalones that I have tried...except the portable.
Thanks for confirming what I was beginning to suspect. The only difference between the two players is that they were modded (for multi-region) by different suppliers. I bought the player a long time ago (when they were a novelty and very expensive). It's not worth getting anyone to look at it since new players are so cheap now.
Well I bought one of those kits and performed a clean and it made no difference. However, just a few days ago I wasn't thinking straight and popped a DVD-R into the player and it worked! I then tried a load of other backups and they work too! This is the first time this player has played a DVD-R. Maybe the clean did the trick after all. Is there an even deeper method of cleaning beyond those strange little brushes that I can try ?
