Hi all!
This is my first post on cdfreaks forums, I was a massive lurker 
I have some problems with my LiteOn 1653s drive, that seem to be already discussed somewhere, but without conclusions.
I use only DVD-R and media are 4x AML (not so bad) and 8x CMC MAG AE1 (nice I think)
With both of them I had problems when the drive wrote the leadin part.
Usually it takes around 1 minute and half to write the leadin, and I can hear the motor spinning up and stopping four or five times.
Sometimes (without any apparent reason) after this period Nero give me a sort of calibration error and tries to write the leadout with no success.
The strange thing is that if I try to burn the same dvd a second time the burn has success.
I found a previous thread talking about this behaviour with firmware like CS07 and olders. I tried with CS0P and (now) with CSTR, but I'm having still this problem.
Sometimes (again without apparent reason) it won't write the leadout part, but this seems to be a Nero 6.6.x problem, so I switched to 6.3.x, and now I'll see what happens.
In spite of these problems, I have nice scannings of the written media, expecially CMC ones.
Is someone experiencing this like I'm doing? 
Tnx all!
