hi all, I am new to this forum as a poster... but I have been reading this for over a month until I recently got my Sony DW-U10A with 1.1a firmware Using RecordNow MAX 4.5, I created a *.gi file from one of my PS2 game. Then I use "test" to test the burning w/ Princo DVD-R 1X (white/silver) media, for 3 discs in a row.. I got the following error for all 3 disc... at around 75-80%, I always got an error like this .. "Error 10 at sector 2084384 - Disc Write Error - Command 2A Sense 03 ASC0C ASCQ:08" Now, I then use the Ritek 4X that comes w/ the DW-U10A and the burning was A okay and the copy was read by my PS2 alright... So.. I wonder why..... I have read that Sony DRU-500A used to have problem w/ Princo but ppl also reported that w/ firmware 1.0f, DRU-500A works fine w/ Princo I wonder should I change my DW-U10A 1.1a to DRU-500A 1.0g ? .. will that allow me to use Princo ? or I better off stay w/ 1.1a (DW-U10A) and stay w/ Ritek ? Thanks all ! B.H.
