If you're really using EyeTV 3.1, please update to the latest version 
of EyeTV, which fixes a known issue in EyeTV menu that can have an 
effect similar to the one you describe.

If you've posted a shortened EyeTV version number and you are in fact 
using the latest version, please send me a screenshot of Prefs > 
Mapping > EyeTV and also let me know

- the OS X version you run 
- the Mac model you are using 
- the remote control you are using 
- the exact EyeTV version you are running (including the build number 
from the About dialog) 
- the Remote Buddy version you are running

Thanks in advance.

Best regards, 
Felix Schwarz
