OK peeps, I stuck the bullet cam on my pushbike handle bars last night and went out for a spin. Had the battery pack in one pocket and the Archos in the other and the whole thing worked perfectly all night.
There's 3 files here so you can take a look at the quality
http://www.desmo.plus.com/video/ sample2.avi is a totally untouched copy of the file. This is the exact quality you get.
sample2small.avi has been compressed slighty just to reduce file size.
samplesmall.avi has is a longer bit of film of my mates trials bikes. Has also been compressed quite heavily but the quality is still pretty good.
None of the clips have sounds as I didn't bother taking the mic out with me. Overall I'm pretty pleased with it all and it'll be more than good enough to grab some trackday footage
