I agree with kabukijo, newer firmware at times f.cks things up. My NEC 4570 with original firmware was doing fine job with Verb -R media, when I upgraded it to the latest it started producing very high P2 errors. I went back to my old firmware and it makes 95+ quality burns again. :iagree:
This can vary with media type, so don't nobody be surprised if some media works better than other.
In my case I keep all versions of firmware ever released and test each with new batch of DVD media I get. This allows me to select the best firmware for each batch of media I use. Sure it is pain in the a.ss but what else can you do... :rolleyes:
Same thing with DVR-112L, I keep all version of firmware and so far the Buffalo 1.21 seems to be the best, at least with the media I use (got some old 2.4x Verbs -R at real cheap, and burn them at 4x with firmware fix. :bigsmile: )
