The following is a copy of a post I made on another string. It might be of interest to you.
I am having similar problems after burning a DVD.
The DVD WILL play on a cheap DVD player but will not play on my main Panasonic DVD Recorder/Player. I keep receiving the message "Incompatible TV System Setting".
I have tried various DVD's (DVD-R, DVD-R/W, DVD+R/W) of various manufacture. All give the same results. Burning slide shows or movies with other programs using the same discs present no problems.
However, and this is the interesting point, If I copy the "problem" discs, using Ashampoo or other copy programs, to any other blank disc, the "newly copied" disc WILL play with no problem.
