I have a project coming up that needs to use an external cam, not the builtin. (Ok, I don't have it working either, but I have not done the homework to feel like a query to the list is justified.)
My guess is that is just the result of trying to record/encode/write
video on a system running a pretty lightweight processor. Even with
2GB of RAM, I have a feeling you're just overloading the processor and
your video issues are due to that. I had the same issues (and still
do) on my Lenovo S10 running a slightly older Atom processor than
yours. I bet if you tried the same camera on a laptop with a core i3,
i5 or i7 you'd see much different results.
You also didn't mention if you were recording in HD or not. If you
are, try dropping the resolution down to something lower and see if
that improves the situation.
