I know this has been asked countless times before but I'm new to this, I've been reading posts during the last 3 days and it still doesn't work. I have a V4 PS2 with a duo modchip. I'm using a Toshiba SD-R5272 (Dual format 8X 4X 12X DVD burner) and various blank medias. (I have some Lead Data DVD-R 8x 4.7 GBs, some Verbatim DataLifePlus DVD-R 2X 4.7 GBs and some Maxell DVD-RW 2X 4.7 GBs) I tried using Nero 22.214.171.124 and the last version of DVD Decrypter and I always burned at the slowest speed possible (with DVD Decrypter I selected 1x but the program burned at 2x because it was the minimum for my discs). I tried backing up different games (Suikoden 3, Front Mission 4 and Psy Ops : The Mindgate Conspiracy to name a few) and the result is ALWAYS the same. With the DVD-RW I get a Read Disc Error and with the DVD-R I get the "Please insert a ps2 or ps1 format disc" error a.k.a. the red screen. I checked the soldering and everything was fine (I didn't do it myself, I asked someone in my family, an electronic technician, to do it). The lens is clean, the ps2 has no problem reading other discs (never tried to play movies in it so I don't know if movies on DVD-R work). I hope I gave enough information.
