Hi all. Has anyone else burned at 4x (Ritek G04) with DVD Decrypter? Does your buffer stay at 100% the whole time throughout the burn?

When I burn at 4x the buffer doesnt' always stay at 100%, it will sometimes drop right down to 0% and then the light on the burner goes out for a few seconds and the LED on my HD also stops as it's not reading.. Then all the sudden it starts burning again as normal.

Both my 160gb drive and my DVR-105 are on the Firewire port so I'm not sure if it can't keep up or what the deal is.. I'm also wondering if this if when this happens it will cause the disc being burned to be faulty. I haven't watched a whole movie yet to test whether it is but just wanted to see if anyone else has experienced this?
