Hope this is of help :
My original black Xbox (Samusung drive) recently died.Fortunately, I have a crystal box (Phillips drive) too but when i softmod'ed it and tried to play my old backup's, it just did'nt want to know
My old box only really liked Verbatim DVD-R's (which i discovered after trying lots of media brands), but my 1.6 crystal would'nt even recognise them.After a number of coasters, i'd pretty much given up on backup's.I had a few Maxell DVD-R's knocking around so thought i'd give them a try and to my suprise they work pretty flawlessly
Anyway, i'd been having probs with constant DDE's on one of the new backup's but had run out of Maxell media so after reading this post, I thought i'd experiment with some DVD+R's that i had spare (Verbatim).I followed the advice on these forums and using my LiteOn drive and changing book type to DVD-ROM in DVD Decrypter, I gave it a try without expecting any success.However, not only did the disk burn without any retries (VERY rare in my experience), it also seemed to burn faster AND the end result works flawlessly WITHOUT any of the DDE's i was getting using previous media
I realise not everyone will have the same luck, but it's certainly worth experimenting.All i use now are Verbatim DVD+R's, burned with DVD Decrypter and changed book type and they all work without fault on my 1.6 crystal machine
Hope this is of some use to someone.
