horndoctor, I tried it, they let you check out a few stations for free, and the TV guide is good (to get all the stations you need to register it).
However, it does require a fast connection, so if your signal is not great, you're out of luck. I chose a station, and it told me I needed 384Kb/s for low quality, but I don't get even that where I live so it was useless. I also noticed that the battery was getting quite warm just after a few minutes of use.
I'm going to try it next time I go to town to see whether it works any better in a strong signal area (near a cell tower with full bars I can get up to 1.2Mb/s but I usually get around 800Kb/s)

Well I looked ity up on spbsoftware's forum and it turns out it defaults to normal quality (sure looked shitty to me!)... I tried again and switched to lower quality (200Kb/s), more compression artifacts but generally better because it doesn't stutter anymore
And yes, it's free, I wasn't clear enough... It's just that if you want to see all 200 or so channels, you'll need to register...
