2 cents from my side as well. Actually, I have posted some of it in Lite-on forum under CDR/RW writers, but it seems that this forum is more appropriate for this subject.
So, my first impressions are not very nice (I have good experience with Pioneer A104 for DVD and Plextror PX24 for CD before). First, it did not accepted any cheap DVD-R media I used before (mostly it was Fujifilm DVD-R 1X with manufacturer info RITEK G03), which were burning nice on A104 at 2X. Liteon burner just did not find media in the drive!
Verbatim 2X brand (MCC 00RG200) and another Fujifilm (which appeared to to be TAIYO YUDEN) worked fine on burning speed 2X in simulation mode - I did not do real burn.
Well, I did real burn on 4x with Intenso DVD-R, which was RITEK G04, and it was OK (playing well on Philips DVD player).
Second, it did not burn any of CD-RW and DVD-RW I used before! It burns, but media is not readable (lot of C2 and non-recoverable errors ). The same media used on the same PC, the same burning SW (Nero 5.5.X), the same burning speed, but on my old Plextor drive works fine - perfect readability, Nero CD Speed tool reports 0 C2 errors.
The same problem is with DVD-RW (I used Verbatim DVD-RW with manufacturer code MCC 01RW11N9) and results are similar - it burns at speed 1x (at 2.4X I got "Write error" from Nero. Nero reports it as allowed speed, but burning fails), but DVD is not readable afterwards.
BTW, from shop it came with Firmware FS02, I met all the listed problems, than I upgraded to FS0F, but problems stays.
So, my overall impression is that drive is not good for cheep DVD-R and definetly not for CD/DVD-RW. Let us just hope, that Liteon will fix some issues in next firmwares.
