With EyeTV 3.4.3, the AppleScript channels property of EyeTV appears to be broken. Invoking it directly returns an error. This hinders Remote Buddy from quick and effective access to the channel list. I'll get in touch with Elgato next week regarding this bug.

I've already found a workaround and uploaded an updated copy of Remote Buddy to the server. To install it, download Remote Buddy here and follow the instructions to replace your existing copy:

If, after installing the updated copy, the problem still persists, please let me know.

An alternative solution then is to create a "Favorites" group in EyeTV (using the + in the lower, left corner of the EyeTV window) and then add your channels to it. You can then access these under "Favorites" in the Remote Buddy menu.

Yet still, please let me know if the problem persists even after installing the updated copy. Thanks in advance.

Best regards,
