What is everyone using to pre-segment files for multi-bitrate VOD playback? We have tried both Rhozet and Squeeze, but haven't had real luck with either. Rhozet seems to be creating an h264 profile that the roku is not real happy with and squeeze fails to do proper key-frame alignment (still testing this). Anyone out there using any other encoders that do ABR HLS? Do the roku guys have any suggestions?

EDIT:

After some more testing we are getting better results out of Sorenson Squeeze (there seems to be some bugs in the software), but are still curious what others are using.

The encoding guide goes into more detail about this, but the Wowza servers seem do HLS segmenting well. The tools with MaxOS X can also segment the files well. The Encoding Guide goes into more detail about this.

We already use wowza for streaming, but that is not what I am looking for. Also the apple segmenter will not make adaptive bitrate segments. The apple segmenter will only segment one file at a time which means you would have already had to create the separate transport stream files. The main hurdle with doing VOD adaptive bitrate is all of the key-frames have to be aligned across the different bitrates so it is a seamless switch between levels.
