Chef - Try telling people who have older dvd players that the requirement for bitsetting is bullshit. Also, I don't suppose you make sure your DL discs are bitset to dvd-rom before you do them? It's odd that Pioneer will include it for DL but not for SL. But then again Pioneer are reluctant to even support +R/RW on their standalone recorders. They are proving to be a company who is very narrow minded. I encourage everyone not to buy anymore Pioneer burners. This way they will get the message.
