I haven't looked into vlc's mepg code, so I don't now what exactly it
does when it looses one or more TS frames.  It just seems to me that 
the hardware decoder we're working with has a better error mitigation
although it is far from being perfect.

A good mitigation scheme and FEC are essential to set up a scalable
distribution system over a (somewhat) lossy network. That's my focus.

I have a lot of code to handle audio (MPEG2/4 AAC). Much of it could be 
re-used to carry MPEG2 Transport. I'm right now trying to convince my
to make that stuff OpenSource.

Same as above. I have some code but need to find a way to make it public

I mainly wanted to get a feeling for what people's interests are.
If I can find a decent DivX codec I might go for that since I'm really
with the video quality at around 2Mbps.
