Sorry I mixed up the specs of HD DVD and BD read speed.

HD DVD read speed is max 3x meanwhile BD is max 5x on the GGC-H20L.

So for a full 30GB HD DVD movie, you're right it can go between 1 to 1.5 hours to rip the movie.

As for the fluctuating speed you see in AnyDVD ripper, because the drive is using CAV methods where it starts at 1.3x (5840 kb/s) increases up to 3x (13485 kb/s) at layer break and slow down again to 1.3x at the end of the disc. Depends on the disc size, not all will reach the maximum 3x speed at layer break as you can see here: http://club.cdfreaks.com/attachments...ere-hd_trt.png
