Pioneer Dvd-rw Dvr-k16rs issue in Acer Aspire 5101 ANWLMi laptop? - http://tdb.rpc1.org/#dvrk16rs

I have an Acer Aspire 5101 notebook ANWLMi. It is a Pioneer DVD-RW DVR-k16rs. The DVD recorder worked well.
My OS Win XP SP2. 6.6 NGDO I use for recording.

A few months ago I had a problem, and it starts malfunctioning.
(FYI: I tried to change the region of the device - 2 changes immediately. Also, the DVD-ROM flashed with the RPC1 firmware update --

However, it would read CDs and DVDs, but does not recognize some other ordinary CD / DVD - even the original CD driver Acer is not recognized.

I can not burn, burn CD or DVD - for a while and then stops. Some error messages are:

# CD: clerical, Illegal disc, could not perform end of Disc-at-once

# DVD: Power calibration error

I had to Google and used some RPC1 is my original firmware is RPC2 type.
Is it possible the firmware RPC2 vice versa? Where can I find? I have also installed "Portable_DVD_Region + CSS_Free"
