Nero Burning Rom - Cannot Mount CD

[bluebear56]

For some reason when I burn data to my cdr using Nero it tells me that during the verification process it cannot mount the cd or something. I tells me that it successful burnt the data, which is very true since I can see and recover using either isobuster or my favorite recovery program CDR diagnostic, however it doesn't display the contents in Disc content in explorer. Why can't it mount the data so I can read it read it like any other disc?

Extra notes:
-Nero Burning Rom 6.3.11.0 or something like that.
-Mitsubishi CDRW Drive
-CDR Diagnostic tells me in the disk report that it says the disc is blank and it might due to a buffer underrun error.
-The Data I was adding was lots of jpg and short mpgs which some of them contained very long filenames. Other Burners Like NTI CD Platinum 6 tell me to exclude this long filenames otherwise I can't use Joliet File System (?)
-The Data also had a lot of the same filenames used for the pictures but were separated in the folders.
-NTI Cd Platium 6 was installed with Nero.
-CDR was a 700MB Media Cache Disk (Nero Had no problems earlier burning some mp3's to these Discs)
-I came across Roxio Easy media creator 7 and installed it, but found it too chucky so removed it.
