If you can play the discs in your Xbox and in your computer but not in your disc player, then the problem isn't with the software. It means that for some reason your disc player doesn't like home burned discs.
There are ways you can minimize this but, unfortunately, not eliminate completely.
* Save your DVD as an ISO on your hard drive rather than burning directly to a disc.
* Use a high quality disc, like Verbatim, rather than a store brand -- and avoid Memorex whenever possible.
* Use ImgBurn to burn the DVD from your ISO file. Make sure the option to verify the burn is checked. When ImgBurn burns to a Verbatim disc and the burn is verified, I've had almost no clients or friends complain they couldn't play the disc.
I have never had this issue with other programs I have used but I will attempt the ISO and IMGBURN option. I will let you know if that works for me.
Make sure you use a good brand of disks like Verbatim or Tayo Yuden.
I know my DVD-R's are Verbatim. Cant remember what the DVD+R/DL were.
