I've read with interest the posts in the sticky above. My conclusion was that -R is generally more compatible with most players. My local DVD hire place no longer hires out original DVD discs as the owner complains of high rates of damaged discs. As a result he makes copies of his originals for hire (obviously copywrite infringement!). He used to copy onto -R so I thought that the purchase of my new tosh XS32 would have no problems playing these discs. Horror of horrors! I found out after getting my player that this chap has switched to using +R. I called him to tell him that these don't play in my superduper fandango tosh. He told me that I should use an el cheapo machine as these play anything you throw at them. Surprisingly, he said that he had to stop using -R as he was getting lots of complaints about non-compatibilty. Ever since he has switched to +R, I am just the second person to complain. This seems to contradict the general consensus. Could it be that -R is more compatible on branded units and +R on no-name brand DVD players? Another interesting point is that this chap removes region and RCE encoding, retains the original dolby digital soundtrack but puts back the macrovision code - obviously to prevent competition!
