The (From 2036 Lounge version) file is an *.wmv Windows movie file - 44100kHz 16 bit lossless - except glitches near the end a couple of times - all the time you upload - glitches from utube.
The other (Riders of the Storm) is *.avi file 48000kHz 24 bit - no glitches from utube uploading.
Had those up before, just leave them up for the heck of it.
The buffalo one is just a cheap HD Ready camera with internal mic on a windy day.
Camcorders have to probably be around $1000 to start getting sorta good and more way more for better equipment.
Still movie edit programs can only do whatever and cheap ones do cheap audio usually although even Windows Movie Maker can make a video (capture also) and have stills and video all on the same video - usually sound does not have all the options, and if more options they usually want a few dollars more for the software.
