Problem win Teac cd rom and D.A.E

[Machamix]

Hi friends. I used to have a 524e Teac ide cd rom, it worked perfctly for about 1 year, after upgrading my pc i decided to buy a new cdrom, a new Teac (more fast i think): i buyed a 532E (32x), well the fact is when i try to "rip" an audio cd to .wav using audiograbber or windac, sometimes (i mean, really don't know when, depends on the animic state of the cdrom player), well the resulting wave file has silences for 1 or 2 secs. in the middle, beginning or ending of the track. The 532E was purchased in necx store and has no documentation.
Any ideas on this?, is really bad my cdrom player?, any experience of incompatibillity with this and D.A.E programs?
thanks in advance.
