I haven’t used the viewer you referenced but I used Shotput pro all the time and love it.
I know this sounds funny and maybe I’m just cheap but I use a HD tv/monitor to play back from the cam when I am reviewing my cuts and taking my notes. I can be log and transferring one card or dumping it with shotput and be reviewing another card on my TV/Monitor at the same time this way. Works for me anyway.
Videos are like Tattoos….
Cheap ones aren’t good and good ones aren’t cheap!
