I may be late to the party, but I bought EyeTV 3 off the US site about 2 weeks ago. Thought it was really good at first, lovely new UI and onscreen menus.
'Cept I left it to record a few TV shows one night. When I got back it gave a recorded time of 0 for all TV shows. The Live TV window was opened so it was all fully operational. Tried recording live again and it gave the same error. I tried exporting 2 clips, one from when 3 was working and one left over from 2 - both got stuck quite early on in the process. Didn't crash but the progress bar just hadn't moved overnight.
Decided to leave 3 for now and go back to 2. But good luck with that! 2 isn't on the Elgato site anymore, I had to hunt down the app via a torrent. Really not happy with Elgato just cutting off 2 like that. To anyone planning an update burn EyeTV 2 to a CD and archive it just incase you get problems.
