I recently tried some of the podcast channels and was very disappointed in that I want to ad my own subscriptions. I decided to take a low-tek approach. I use RoksBox to stream from my desktop. I set up a sync program (synctoy 2.1) to sync the video podcasts iTunes library to a folder on my mongoose server (RoksBox). I have tested this on about 10 different podcasts and it works so far.

Anyway I thought I would pass this along.

There is a itunes podcasts private channel that I think you can search in.

iTunes has the entire iTunes directory available.

Mediafly and CDNTwo let you enter your own feeds.

Yes, I tried the itunes channel, I found that it was having issues playing the majority of content. Could be my connection or where the channel is hosted from. I also tried CDNTwo, but I may give this another look.
Thanks for the feedback.

I found the itunes channel to have minimal choices available from their store. Everything I find on the itunes store doesn't turn up on the roku search. : (

Can you provide some examples? The iTunes Podcasts channel searches iTunes directly, so there shouldn't be any podcasts in iTunes that can't be found in the channel.
