dvrcast load times - is HDS a solution?

[N_Tyler]

We are streaming H.264 video to the dvrcast application using RTMP streaming.  Everything is working fine, though we are noticing some unacceptable load times when loading large videos for playback that have been recorded this way.  I found http://forums.adobe.com/message/3399973#3399973 which offers some suggestions.  I will be looking into post-processing the video to defragment it, but I'm also interested in HDS.  Is it possible to use HDS with dvrcast streams that were recorded to mp4 via RTMP streaming?  I tried the HDS URL convention - http://server/dvrcast_origin/stream_name.f4m but this isn't working.  Are there other suggestions for improving load times for long videos with the dvrcast application?

Additionally, I can't seem to get the F4V post processor to work with these files.  It is throwing an error "cannot open file" and the -v flag adds no helpful output.
