4231 error code
Hi joe !
My HP Notebook has a built-in TSSTcorp CDDVDW TS-L632N 0503 152.
It has worked flawlessly from the day I got the system (a little over a year ago).
I would doubt it is a drive problem.
I'm also using Windows Vista Home Premium SP1.
I'm a little confused by your statements.
On the one hand you say YOU wrote the software, but on the other you say your using an LS Template.
Did you write a program using the SDK?
Maybe you're not using one of the API Calls incorrectly!?!?!
