I have exactly the same problem im the TDK DVD+R with the same mid code (which should be a supported one)and the disc can also only read fluently by the PC in the xbox there is no chance to get it running and my 2 stand alone players get freezes till it freezes completly i tried it 5 times (using Fw 048 and nero 5.5 and later i tried again with 6.3 but no luck)
With the sony burner the same media can be read by the PC, Xbox and the SAÂ´s(yes the have the latest available firmware and the are normally reading everything from the cheapest to the expensivst dvd/cd-r media).
When i check the discs with nero cd/dvd speed with my liteon dvd drive the line gets at the end like a rollercoaster ride. (ok when i do the test with the btc drive i get an perfect result)
That sucks cause i think i am using not the cheapest media with an by btc officaly supported mid code and after burning i am getting a fully written media which i can only use on my pc.
