Burned Dual Layer Disc Not Recognized In Xbox 360

[poover]

I'm trying to burn a WMV HD file, about 6 GB, to a Verbatim DVD+R DL disc. Each time I try - the 360 dashboard does not recogize the disc; it goes from 'readin' to 'open tray'. It *should* show up as "mixed media".

I've tried:

Nero 7 Ultra Edition:
UDF/ISO (DVD-ROM) with UDF 2.01 file system

ImgBurn:
DVD-ROM

I was sure to close the session each time, too; no 'multisession'.

NOTE: The file plays fine on the 360 when I stream from PC.

Anyone have experience with this?

Hah! Got it to work by selecting "Enable Xbox compatibility mode" under the UDF tab in Nero - if anyone cares :P
