TSSTcorp TS-L532A firmware request / problems reading DVDs

Hi,
I have a TSSTcorp TS-L532A which came in my Asus M6Ne laptop. I have had it for just over 2 years and have had endless problems with it. I came to accept that it was very fussy about what media it accepted and that it often fails. I have accounted for this by burning at slow speeds and always performing data verifications after burning.

I have now come to realise that many of the DVDs that seemed to have burned properly and passed the data verification cannot be read by L532A. Most DVDs I am running into problems with have large videos on them. I am able to play the videos without problems but when I attempt to copy the entire video file to my HD I run into errors (often cyclic redundancy). What makes this even more frustrating is that these DVDs can be read without problems in other drives. I can even copy the files to the HD without any problems.

This leads me to believe it is a problem with the firmware/drive. I have looked around on the net A LOT and there seem to be many people having problems with this drive. However, I cannot find any solutions or firmware for the drive. I currently have TC51 firmware loaded.

Does anyone have any suggestions/solutions? Are there any different firmware there I should try? Or should I just look into getting a new drive?
thanks in advance...

Clean the drive and use reliable media.

The drive has been cleaned and I am talking about various brands of media that have burned successfully, passed data verification and can be read but not copied.

IF a disc can be read that it CAN also get copied.

Exactly which media and content you are talking about?
