ok update, i burned a disc whit no other programs running and the buffer stayed full. now the only program I usually have running is grabit and it is downloading all the time. i have 6 sata ports on my motherboard. they are labled as 2_0 2_1 and so on. I have the hdd and the pioneer burner on 0 and 1. would it help if I changed the pioneer to its own channel. any ideas are appreciated
