The first video was shot using the ELMO SUV Cam MPEG4 recorder on Ron Trotter's IS '82 911 Targa during the morning practice session...not the greatest or fastest lap, I think it was a 113.34 . I haven't watched it yet, just uploaded it.

This next video was shot with the ChaseCam PDR100 MPEG2 recorder with G-Force overlay (live) as rented by Gunter Enz and son. I will upload it shortly and add it to this thread.
I know Sean Steele shot video with the PDR100 in 944Spec, as did David Gardner in his 993. Post them here!
