Ok, so which videos format are yo most interested in? Since you started with 
ffmpeg yourself, I guess that fits your needs, right?

Err, this is what I started with, and it's very easy because in DV every frame 
is compressed independent from each other frame. No bother with I- F B- 
K-Frames and what not. It's a very good format for video editing, also 
because it has very high quality. Ok, downside is, you need 8 Gig for one 
hour of video. But then, IDE-HD is cheap these days ;-)
The actuall editing is done in uncompressed RGB or YUV anyway, so given you 
have a decoder which gives you plain RGB frames it doesn't make any 
difference which format they have been in.
Unfortunately under linux you have to understand and write interfaces for a 
lot of single libraries. I started with libdv, and thought all the others I 
get for free when I interface to GStreamer, but that might take a while.
If you and Jason don't usually edit DV and don't even have DV files for 
testing, then supporting your favourit format is a high priority goal, if you 
also use DV, then I would say it's medium or low priority. 

Cheers,
Rolf

P.S.: Until I (or someone ;-) implements the libav{codec} interface you can 
use a small DV sample file. It is 7MB (50 DV frames)
