Hi Albert

Thanks for your reply. I've tried the new firmware and with the supplied 
aerial, but with no different results. I haven't changed any source code 
- at present I wouldn't know how, I'm still learning. I understand, 
though, that the eeebuntu kernel is a modified one called the array 
kernel, if that makes any difference. I tried Kaffine and Me TV first 
and found that neither could detect any channels, which is why I decided 
to try the dvb utilities from the wiki. Thanks for the suggestions, though.

Can anyone give me some advice on how to find out why I get the 'filter 
timeout'? Is it because there is no filter to be found, or because there 
is no signal from the tuner, or because no channels are found within a 
given time...? If it's the last of these then it isn't trying for long 
enough, as it takes a minute of so for the first channel to be found on 
a Windows system and the filter timeout occurs after a few seconds.

Regards

Sid
