Hi all, I have a Xbox with the dvd player kit but it will not play dvd that have been recorded, specifically DVD+R/RW. I checked on DVDplusRW.org compatibility website and the Xbox is listed as compatible. Why won't the recorded DVDs play? Also, I've been looking at buying a seperate DVD player for under $100. Wally World has a Sony for $75 that lists all of the different CD and DVD formats on the box so would probably work for me. I've read better reviews about the Pioneer DV-578A or DV-588A but they are not on the compatibility list for DVD+R/RW. How reliable are these compatiblity lists? Would I be better off just to get the Sony? Please advise. Thanks.
