UDF/ISO Hybrid discs work –
I downloaded SMS v1.4 and installed it. Then I put in some of my CD-Rs that were UDF/ISO format and they worked fine. I also tried my DVD-Rs that were UDF/ISO and they worked too.
If it doesn't work for you then it's a problem with the media. I put in 5 different kHypermedia cds and ps2 woudn't recongnize them, they would just keep on spinning. Then I tried some cheap no label CD-Rs and they worked fine. My DVDs were TDK, BTW.
