I just finished testing with the drives.
The LG GGW-H20L I already built in my work PC, because it was too loud for the HTPC anyway.
Next to try was the LiteOn DH-4O1S. At first I was disappointed, as it was a bit louder than the LG. I remebered that I read over at slysoft, that at least the Pioneer drive is not supported from the AnyDVD Speedmanagement. I thought I give it a try on the LiteOn and IT WORKS!!
The LiteOn drive with setting “Slow and Silent” operates BluRay 1x and DVD 2x (CD not tested). With BluRay its not hearable in 3 meters distance in a dead silent room. And with DVD almost not.
CD-Bremse is also working allthough I didnÂ´t test with this very much.
I gave then the LG GGC-H20L a try, but it was as loud as the GGW and tried with it the speedmanagement, but its not supported.
The Pioneer BDC-202 I left unopened because I am happy with the LiteOn and it canÂ´t be les audible than non-audible and its not spported from speedmanagement or CD-Bremse.
So the LiteOn DH-4O1S is the ultimate HTPC BluRay drive (in combination with AnyDVD or CD-Bremse.
