I'm not sure if this will work on the Neuros tablet, but when we started out
we created ogv files from the RecordMyDesktop and then had to convert them
to avi to put on the site. We used mencoder for this (and not ffmpeg). We
had a script that was uber-tweaked by some mencoder guru that heathenx found
out on a forum somewhere. ;) The script was this:

nice -n 0 mencoder original.ogg -ofps 26 -vf scale=912:684:0:0::::0:1 -sws
10 -af resample=22050:0:2 -srate 22050 -oac mp3lame -lameopts
cbr:br=128:aq=4:vol=1.5:mode=1:highpassfreq=0:lowpassfreq=0 -ovc x264
-x264encopts
qp=2:me=hex:nodct_decimate:nointerlaced:no8x8dct:threads=1:nofast_pskip:nobrdo:trellis=1:scenecut=40:chroma_qp_offset=0:ip_factor=1.4:pb_factor=1.3:nomixed_refs:noglobal_header:nobime:keyint=250:keyint_min=25:frameref=1:bframes=0:nob_adapt:nob_pyramid:noweight_b:subq=5:chroma_me:nocabac:nodeblock
-o output_file.avi

Boy that's ugly huh? :) The only thing  that may change is that the scale
value shown (912x684) was what we originally used for our video size, but it
subsequently changed after that to something else. You should be able to
just change those numbers to suit what the original video you're converting
actually is. I think our later episodes are 880x656 or something like that
(we were told to maintain sizes that were a factor of 16 for maximum quality
so that's why the sizes are weird).

Anyways, install mencoder if you don't have it already and give the above
script a shot. As with pretty much any advice I ever give.. no guarantees.
;)
