victor- does ITVC always output the same video properties, regardless of the input-- i.e. whether I throw a 1900x1080 video or a 640x480, that ITVC will transcode to 400x240? How about bitrates for video and audio- does ITVC have a static setting that's optimized for our tablets or does that vary by the type of video input?

I'm pursuing parallel paths here-- the author of mcebuddy may be willing to add a configuration setting for video output support for the N810's since he's got the conversion of dvr-ms's to pretty much any format (but not n810 friendly settings) in his code, while you've got the n810 friendly results but aren't dvr-ms friendly yet.
