V0457 firmware

I had lot of problems with DVD-R and v156, v256 and v356 firmware. Since I use the 0457 firmware version I have no more problems.
I’ve burned 10 RITEKG04 at 4X with success. All my DVD’s are read on an Honer, Kiss DP450 an P2 DVD players. This firmware seems to be a rock.
The best results I had since I bought my BTC 1008 are with RICOHJPN DVD+R with wich I have no compatibility problems.

Did somebody tried 0557 ?


Sorry for my bad english
