I found the answer to my own question by searching the forum again last
night. I manually installed the upgrade kb930194 and restarted. Now drive
is recognizes blank dvds/cds and will burn.

I bought a new computer with with a TSSH corp TS-H652D dvd-rw drive. the
drive worked fine when I got it with Vista home premium preloaded. I
upgraded a few days later to vista ultimate and now the burning capabilities
of the drive are not recognized by any of the included MS applications (DVD
Maker, Media player, Media center etc). I have no third party burning
software installed. I have been in contact with MS support and they have
walked me though an in place upgrade, a complete custom install after
formating the hard drive. We have tried searching for new drivers, firmware
and have been unsuccessful. I have read about deleting the upper and lower
registry files but they do not exist on my computer. There are also missing
registry files for cd/dvd burning in the registry. MS is still researching
the problem but it has been 2 weeks and no fix. I was wondering if anyone
else has had similar problems or knows of anything else to try. Any
suggestions are appreciated
