OK, DVR is now flashed to 1.37 = Still can't burn DVD+DL!

Question

I have managed to flash my Pioneer DVR 110D to firmware revision 1.37, confirmed in Sys Prefs and all. Still, iDVD5 will not recognize it as a DL burner... I get no pop-up anywhere allowing me to change to an 8 Gig disc. Anyone have any ideas?
Yes, in ATA it says:
PIONEER DVD-RW DVR-110D:
Model: PIONEER DVD-RW DVR-110D
Revision: 1.37
Detachable Drive: No
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal
And in Disc burning it says:
PIONEER DVD-RW DVR-110D:
Firmware Revision: 1.37
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2000 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW, +R DL
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: No
...but iDVD5 won't give me a pop-up to burn DL and any attempt to burn or save dead-ends me with:
"Your project exceeds the maximum allowed content duration. You will not be able to burn your DVD."
I did a total shut down and restart, ran disc utility ot check permissions, etc., and nothing seems to work.

As a deperation measure, even though I had already updated iDVD 5.0 to 5.0.1, I downloaded and tried the updater again. Lo and behold, the 8Gig option pop-up returns! I'll never understand computers, but I hope this helps someone else out! Never discount running updaters a second time.
