I personally have not had any problems with the few pressed DVDs I have used in my 2500A. However, it does not read back the DVD-R or DVD+R discs it burns very well at all! Nine times out of ten I get errors when performing a verify in Nero - and I only use the best DVD media (Usually Verbatim MCC01RG2, MCC02RG20 or RICOHJPNR01). I don’t have problems reading these disks in other drives , however.
I think my instance of the 2500A is slightly poorer than most in terms of DVD reading, but generally speaking an average 2500A/2510A does have poorer reading abilities than most other DVD writers on the market.
In terms of noise, my NEC drive is pretty quiet. Probably slightly quieter than most other DVD drives I have used.
