I first posted this back in the newbie forum but got the advice to try here so I will do that.
I have a nec 3550a (made september 2005) crossflashed to a 4551a and running the original 1.08 firmware on it. The discs I’m using is verbatim 16x tyg03 dye, also tried with some tdk dvdr-r’s. My 4551a will recognize the burnt discs as a blank media with 0mb available, my dvd-reader which is a lite-on is able to read them a bit, but not very good. It manages to read 2 of the data dvdr-r but sometimes it wont recognize them and I have to eject and put it back in. I made an iso of one of my dvdr movies, I mounted it with a virtual drive and it works flawless. Then I burn it to a disc and my dvdrw wont recognize it at all while the dvd-rom will recognize it but when chosing subs it freezes so obv its also have problems reading it. As my dvd-rw cant read it I’m unable to scan PI/PO errors.
I crossflashed it back to a 3550a and updated the firmware to 1y6 rpc1 and burned another dvdr at 8x to a tyg03 discs and its exactly the same. As the 3550a wont read it I put it in my my dvd-reader, lite-on XJ-HD1665, dont know how good of a scanner it is (its prolly shit). Then I did a scan in dvdinfo pro for pi/po errors.
PI Total 8660538 | PI Peak 1674 PI avg 939 || PIF Total 738163 | PIF Peak 188 | PIF avg 28
did another scan on another disc with same movie with the same dvd-reader and it had similiar values, only PIF avg 16.
that surely is unacceptable, is my best bet to get a new dvd burner? Or can something else be messing with my dvd units, except for my dvd-reader being a bad PI/PO scanner?
Very greatful for any help!
