[Redbutton-devel] [PATCH] Less strict frequency check

[Mario R. <mar...@go...>]

I've noticed that Kaffeine tunes a channel up to the nearest kHz, while 
scan generate a channels.conf with frequency exact to 1 Hz.
That implies that when I watch TV with Kaffeine I get this error from 
rb-download

[andrea@thinkpad tmp]$ rb-download -vv 4164

We might need to have a less strict check on the frequency, where we 
only check "frequency / 1000".

What do you think?
