Elgato silently removed support for their own Game Capture HD in the latest version of EyeTV, 3.6.8. This is not mentioned in their release notes so I found out the hard way after upgrading. Elgato, why did you remove support and remove it without warning!?
But they were nice enough to provide a KB article about this with a link to download 3.6.7. I hope they change their minds in 3.6.9 otherwise I will be stuck at 3.6.7.
