hmm..  I went with high quality discs, and I cant seem to get anything to work properly at the slowest burn rate, which is 10x for me.  Few years ago, I was able to burn at 1x and 2x and those discs work fine.  I dunno.  I am buying what I can as I find the higher priced games, and replacing all CDr games I burned.  But, still have some I play.  Like Beyond Shadowgate, my burn works perfectly.  But Dungeon Explorer II wants to be a little bitch.  lol.  Luckily I just got a good price on ebay for that one.  So, I am working towards my goal....Then its on to world domination.
