thanks for posting.

Please elaborate a bit more, so I can get a picture of the whole 
scenery:

1) Which part of Remote Buddy / its menu does feel slow to you?

2) What do you mean by deactivating the "hardware accelerator"?

3) Is EyeTV running at the same time? What is it doing (recording/ 
playing/watchine one/several TV channels)?

4) Have you had a look at where the CPU time and memory is spent on 
your computer using Activity Monitor?

Thanks!

Best regards, 
Felix
