Like a month ago I bought a Pioneer 111. Since then I burned something like 50 DVD+R without a single coaster.
Yesterday I crossflashed the firmware to a 111L 8.29 (http://forums.speedlabs.org/index.php?topic=1082.0)
Since then I’ve tried to burn 5 DVD’s and only one worked properly. The others failed the data verification (by nero 6.0) and the transfer rate test (Nero cd-dvd speed).
The media I used is exactly the same I was using before.
Is it possible to come back to the original firmware? If yes, would that help?
