Someone mentions there that he has similar ptoblems to me. I used the hacked fw for a long time but the results were pretty much the same. I ruined princos using the v1.30 2x4all+RPC1+12 rip, but reverting to the original one had the same results. The hacked fw just unlocks I think the 1x limitation and not the compatibility with the media dye. I have read for a long time ago all the posts at the rpc1 forum (before I post here) and came to the conclusion that some burners can write "non" listed medias like a charm, BUT others not. I may belog to the second category. And I think NIL, Gradius and dhc104 there know that better than I do. I guess I was so unlucky to buy a DVR of the "B" production parts of Pioneer?
