I made some video recordings this morning for a client on my little Aiptek 
camcorder. Its recording HD 720P. When I open the video up with MPlayer I can 
view the video but its just a bit choppy. A small little error box is constantly 
popping but: AVC:nal size 0.

There are two other video options: D1 (DVD) and CIF (Web).

I tried each one and the CIF plays more smoothly than the others but still has 
the choppiness and the error box popping up.

As a note: I tried looking at these videos on my XP laptop and Apple Quicktime 
didnt play it any better.

Unfortunately there is no other option than mov.
