Problem with Pioneer DVR-105
 

Just got my drive a while ago... burned 2 good discs after upgrading to the hacked 1.30 firmware. Both discs were princo 1x and they both burned fine at 2x.

The 5 1x princo discs i've burned after the first 2 all have bad files at the end of the disc for some reason. By bad files I mean files that can't be read by the burner, dvd-rom or dvd-players.

What could the problem be?!?!?! I'm so scared the firmware has damaged the burner...

You should ask this question at the forum where they made this
firmware -> http://forum.firmware-flash.com/

A friend of mine burnes 1x Princo at 2x and they work fine, i would never use 1x Princo. I hope someone answers my question to the use of 4x Princos and their quality.

It should not have done any damage to you burner, but if you are afraid of using 2x4all then just reflash it to the original firmware using the /F switch....... not /f.
