Sorry bud you are right, my mistake. I need to put my glasses on
You have the LTR-48246S with the MediaTek 6 chip and not the LTR-48125W with the MediaTek 5 chipset. However the S and W distinction is still correct (it comes from LiteOn BTW

).
Now to your problem.....yes, since you have the 6 chipset it should be comparable to the LTR-52246S. But just because it is not listed, does not mean it will not work.

"If your CD recorder is not listed, simply try to apply CloneCD. MOST CD-RECORDERS WORK WITH CLONECD, EVEN IF THEY ARE NOT LISTED!"
Since all the recent (since 32x at least) have been tested and have the same results..... RAW-DAO 96, 2x sheep rating on Buffer-Underrun Technology & Correct EFM-Encoding, RAW+96 as best Read and Audio modes..... it should work with full software support.
Have you tried it? Personally, I think Ollie just needs to update his list
