Hey, I just discovered this editor recently, so far it looks like it does an excellent job with pretty much any mpeg converted stream I throw at it.
Seeing as you already are supporting the dishpvr streams, I am wondering if you guys will consider supporting tivo tystreams as well, both from directv tivos (satellite receiver integrated) and standalone tivos. As you probably know by now, tivo tystreams are mpeg-2 transport streams (although I have been told they more resemble program streams) packaged in a somewhat proprietary format.
I know your project is commercial and that you probably want to go wherever the money is, but I am not a market expert, so with that in mind I am not quite sure what to say about the commercial market for tivo owners. However I can tell you that there is a very good sized tivo community called deal database with many people interested in video extraction and editing. You can find it here.
Now there currently are a few freeware tystream conversion tools. One called tystudio is open source and it does a good job of processing the streams into good standard mpeg but it hasn't seen any updates in a while. Another called tytool is closed source, sees occasional updates, and has many features but it can't always convert tystreams to proper mpeg-2, and the author hasn't shown any interest in correcting these issues either, thus you can't use any of the streams it creates in any other editor without encountering severe problems (except videoredo of course, yours seems to do a good job of fixing the mpeg errors that tytool produces, although it does an even better job with the tystudio processed streams as I mentioned here.)
Over the last few days I have been giving your software quite a bit of praise (both here and here) as it seems to work quite well with tystudio processed streams and a few people seem rather interested. Based on what I have seen so far, you can probably do a much better job with the raw unprocessed tystreams than all of the freeware editors currently do, and seeing how you make frequent updates it would probably generate a lot of interest in the deal database community.
I know you already have a lot on your hands with some other features you already mentioned you are going to add, but if it isn't too far out of your way I would like you to take this into consideration. I have a few sample streams I can send you if you are interested.
