DVR-A07XLB subchannels?

I’ve just bought me this drive for backing up my PS2 games. But i’ve read that PS2 needs subchannel, but i can’t select subchannel in Alcohol or CloneCD. Is it true that it doesn’t work? Maybe with a new fw? If not, i’m gonna trade in my Pioneer (anyone has good idea what burner is best for ps2 -> needs to burn ritek g04).
