I did. I use verbatim DVD-R. The same kind I use to burn gamecube games and play them on wii. I have a question. Is it possible to put more than 1 PS2 ISO on a single blank DVD? I know you can for gamecube games but I haven't read anything about it for PS2 games.
Bummer, old console - old laser. You could possible tweak the potentiometer on the laser, or turning those white wheels.
The skipping have nothing to do with McBoot/ESR and is most likely a laser/reading issue.
Multi-game disc is possible, however I never attempted it. The process was a bit lengthy iirc. Do a google search on 'ps2 multi game creator kit'. That contains instructions/programs and what not. DVD Decrypter is basically a old old version of IMGBurn.
