This is not a solution, but I have been experiencing this myself since up-grading from windows XP to Windows 7 Home Premium.
I last used Roxio 6.1 and had no problems, however Roxio 6.1 is not compatable with Windows 7.
There seems to be a lot of issues with DVD burners or CD-R drives with Windows Vista (all versions) and Windows 7 (All versions)
In most cases the upper or lower filters are not even present in the CDROM settings of the registry. (So thats not always the problem or solution)
So it also appears there isn't a commen FIX to address this commen problem with DVD Drives or CD-R Drives.
As for firmware upgrades. it really truely depends on how old the drive is and how much of a fix the firmware update represents.
There are also a lot of issues with error 0xC0AA020F which regards the drive in question as being media mismatched= The media's speed is incompatible with the device. This may be caused by using higher or lower speed media than the range of speeds supported by the device.
Also Error 0X80780048 is a commen back up issue.
The MSDN web site has a link to a hiarchery of sub links concerning IMAPI drives.
Here is the link to the IMAPI return values page, you can work backwards from this link if needed, just use the links on the left side in the hiarchary.http://msdn.microsoft.com/en-us/library/cc835244(VS.85).aspx
The main menu is at this link (it explains ISO9660, Juliet format and UDF)http://msdn.microsoft.com/en-us/library/aa366450(VS.85).aspx
