Get hold of cdparanoia for Windows, or try cdparanoia with the '-Z'
flag, or using 'cdda2wav'.
Testing with either of those should confirm my belief: RealPlayer is
not trying hard to keep audio in sync, while cdparanoia is.
Now, if all you care about is getting the audio onto disk quickly, go
ahead and use the '-Z' flag, or 'cdda2wav', and live with the mostly
inaudible errors in the output.
Personally, I feel that getting the audio *correct* is worth it, since
it doesn't add that long to the rip process, and it does enable me to do
so only once with confidence.

That would be because you have an IDE CD drive, my friend. Once upon a
time there was a "SCSI Emulation" over the IDE disk but, these days,
people just send ATAPI commands over the IDE bus directly.
