I have the above setup on my Mac Mini.

I have an issue with teh change channels on remote buddy. When I am recording through the 2nd channel and watching the first channel I cannot change channels using remote buddy as it comes up saying that something is being recorded so I cannot change channel. 
Looks like it is sending the wrong command as it does not understand teh dual channels. 
The remote with Eyetv/Migalia has no such issue.

any ideas? 

thanks for sharing!

This is a known problem and I'm working on a solution.

The problem is already fixed for some time now. As there is currently 
no way to detect

1) whether EyeTV has several tuners available for recording 
2) how many of them are already recording

the only option I can offer to you right now through Preferences is 
to turn off the check in Remote Buddy altogether. You can do that at:

Preferences > Behaviours > EyeTV > Options

I've setup the EyeTV behaviour with the buttons mapping as per the default. The issue is the now when I get the "you can't change channels" error from EyeTV itself, I can't use the remote to dismiss this error. EyeTV does not seem to be getting the commands from the remote. I've tried setting the EyeTV remote mappings to the virtual remote but this just seems to control iTunes, not EyeTV. Weird.

Now I have to get up and use the mouse to dismiss the error. Quite a pain.

1) The option you turned off usually prevents you from the situation 
you experience. However, since it can't know about the number of 
receivers you have at your hands, it'll keep you from channel 
switching as soon as it detects a recording (which, in its own right 
is already not easy as there is no official support for detecting 
this). I'd love to add detection for these circumstances, but right 
now, I'm unable to do so unless elgato decides to make additions to 
their AppleScript interface.

If you can give me the USB vendor and product IDs of your TV hardware 
(find them in System Profiler), I may be able to implement a smart 
workaround, though.

2) EyeTV does only respond to the Apple Remote (and thus the Virtual 
Remote) when its video window is active. Otherwise, it'll let the 
system handle it.

3) Due to one of the bugs in AppleRemote.m, which many (most? all 
except RB?) people are using to support the Apple Remote, you'll want 
to be sure to start Apple Remote supporting apps only after Remote 
Buddy has launched - as otherwise they will not detect the existance 
of the virtual AppleRemote (and/or loose control over the Apple 
Remote after a sleep/wake cycle). I don't know whether EyeTV does or 
doe snot use that sourcecode as well, though. But this just as a 
general info as it may play a role.
