I have a rear entertainment system on my 2008 Jaguar xj. I've been trying to get some dvd's for the grandkids to watch on trips but I'm getting disc errors on many dvd's. To be clear I do have some dvd's that do play but not a lot. I have had this issue on some older dvd home players with newer discs so I'm thinking this may be due to the older player not being compatible with certain dvd formats. Has anyone experienced this issue and more importantly does anyone know what format the older Alpine dvd player uses?
