I'm having trouble playing my copied dvds in the car. The dvds play fine in the house, but keeps giving me an invalid dvd format error when trying to play them in the car. I burn using dvd shrink and Nero. Any settings I have to change while I burn? Or is it something different? I do have my avic modded with the bypass.

I use dvd43 and 1click copy pro. I dont have any problems at all with the movies working. Make sure you are burning them as dvd's and not vcd's.

Try using DVD -R if you arent already. I has issues with DVD+R
