I'm curious, last night I was only able to get about 90 minutes continuous recording time at 16-bit .wav raw capture with a fresh set of 2300 mAh NiMh batteries using my Lexar 80x 2GB card and an external Sony stereo mike w/plug-in power. Seems like about 1/2 of what others are getting with their R1s running NiMh batteries. I'm doing some comparison testing, but perhaps this is the issue that Edirol has with the current consumption of Lexar 80x cards.
