In my opinion the HDP2 is the best hands down......but I am a little bias. I can record at any bit rate without issue, auto split at user set 1/2 gig( don't quote me), 1 gig, 1.5gig or 2gig. Very easy to use, power, set up blau blau blau.....with 8gig cards being cheap and large cards starting to come out it is a no brainer... peace JK
