I got tired of VideoReDo crashing on almost every single PTV edit... I started using "QuickStreamFix" (Handy VRD Tool) and the problem vanished. What does QuickStreamFix do? I'm sure I don't have a clue, but it does something to fix something that's not right in SD's PTV Streams... that much is certain.Maybe you are currently limited by the State 1.5 issues, but one thing I've noticed between the ATSC streams and your IP streams is the snappiness when scrubbing through in VLC. Trying to play your clips often gives me a second or two delay after repositioning the timeline. While ATSC (and even my own Handbrake files using constant quality) don't have that same kind of delay. I don't know if that is something you can clean up, but it would be appreciated.
Some of my 1280x720 handbrake files are easily under 1GB per hour, and yet they have quality and snappiness better than the streams from Silicon Dust. Of course I'm not putting them into a transport stream either, so maybe that changes things slightly.

Note: I assume the 'fix' it's applying does the same important stuff for AVC streams as it does for MPEG-2 streams 'cause after I use it on a PTV Strream VRD runs flawlessly. Without using it the experience is quite painful.
