question about c2 errors, plzzzz help!

[GizmoC]

I use Nero and LiteOn 2410B

I've been doing some research and testing and I've just releasied that I am in a huge shit.

I have a collection of over 1000 CDs (movies and games) and over 95% of them have been copied on Imation (CMC Magnetics) and Datalife discs (mm&m)

Now, what I've found out is that CMC make really crappy discs. I did various tests on various discs using CDspeed and they reported thousands of errors!
Infact, I tested a few for errors IMMEDIATELY after burning them.. the CDs werent even 1 min old and CDSpeed still showed thousands of errors!

I really treasure my collection and my PRIMARY and ONLY CONCERN IS "longetitiy".

Will these CMC discs last long?

I've heard of errors called "c2 errors", the errors report by CDSpeed are C2 errors or some other type of errors?

Also, is there a way I can correct these errors?

If I get better uality media and copy CD to CD will these errors also be copied? or should I first copy to harddisk and then copy them rather than CD-to-CD directly... would that help?

Over a period is there a tendency for these errors to "spread", if yes, what can I do to prevent it? I mean, these CDs are just like a collection, I dont plan on using them much at all. So, if I just keep them safely inside my cupboard will these CMC discs deterioate over a period of time?



AND ONE MORE THING: Could it be possible that my CD writer is to blame for these errors? Because my cousin burned a movie using those CMC discs using his Plextor and it didnt give any errors.

Thanks! Really looking forward to a reply.
