I need to know which is the best CD-BURNER software for my TEAC 52x
CDRW. EVERYONE recomands me new software everytime i ask my friends. I
need some advice from a professinal.

I've been using Nero for years and have never had any problems with it. 

In general as per my knowledge NERO and ROXIO are the best.

Hi!

I also have Teac 52x CD-writer. I'm using Wicrosoft Windows XP and
Nero, and I have successfully recorded more then 100 cd's withouth any
errors(according to software)-(just a lot of home videos) and Nero is
the best sofware I have used.

New versions (6.x for example) has Nero Smart Start, so you can use
this software withouth any problems, and if you are more professional
in this, you can still use normal Nero Burning ROM. Nero also has
support for many different languages.

You can get Nero from:

http://www.nero.com/en/index.html -main Nero site
http://www.nero.com/en/nero-prog.php -download site
http://www.nero.com/en/sp_file_main.php -language packs

I think if you will choose Nero, you won't have any problems at all.
Price for Nero is about 50?, but you can try demo first.

I forgot to mention, that Nero is well supported on older cd writers
too, and even on new cd and dvd writers (on my experiences).

I hope i didn't mention the wrong price for the program.

I also am a fan of nero.

I just bought a new CD-burner from www.ezpcshop.com with free nero
oem, and its been great, even picked up my old 2-speed philips drive!
(before I removed it)

try Neromix..  part of Nero Burning Rom.  Very simple and effective.
