not sure if this is in the right place but ill try it. i have 2 computers both with the same op system winxp media center edition. 1 comp has powerdvd 6 the other has powerdvd 5 that i paid for through microsoft web site it didnt come with it or wasnt installed when it was built. ok my problem is when i backup my dvd to my hard drive it dosnt convert the vidieo_ts files to mpeg on the comp with the powerdvd 5 on it. what could be the problem do i need to go to a newer version of powerdvd. the other computer works fine with no problems at all. the programs i use to back up my dvd's are dvdfab decryptor and dvd shrink.
