Hauppauge HDPVR -> iTunes without transcoding?

I have EyeTV and a Hauppauge HD-PVR 1212. It seems that most of the HD channels I receive are 1080i. What I'd like to do, and part of the reason I bought the HD-PVR, would be to repackage the mpg program stream as an mp4, since the video is already H.264.

Eventually I'd like to automate this, but currently in all my manual attempts I've had some trouble getting the re-muxed files to open in iTunes. When I drop them on the app, nothing happens. They play in Quicktime Player, however.

Has anyone had any success in doing this? I'd like to avoid transcoding with something like Handbrake, since it's a slow process and in theory iTunes.

I've tried a number of different techniques for the remux, the easiest right now is to use EyeTV's Export to h.264, which repackages it as an MP4, but that doesn't seem to work.

Any suggestions?

thanks! I managed to find the switch on my comcast box to force 720p output, which seems to do the trick. For whatever reason iTunes doesn't like 1080i.

I've a convoluted script that uses FFMPEG, Mp4Box and Subler to create a file for iTunes. It doesn't work 100% of the time, but it's close. If I get it working more consistently I'll share it!
