Hey guys, I'm new here. I have been backing up some of my DVD's for some time now. I recently installed powerdvd 7. It somehow changed my dvd video files to mpeg files. I uninstalled pdvd7, now when i look at the video files it says some of them are PDVD file type. None of the DVD's I back up now work. They work fine on my computer...it recognizes it as a DVD and everything. They dont work on my home DVD player though. I appreciate any help.
