This is what I suspected - I've never looked into bouquets in any detail
Besides, bouquets/presets provided by the network providers (even if they were
usable) would probably not actually correspond to what people really want in
my experience :)

Yeah, I agree - keep the presets seperate from the channel listings. Hopefully
using your other suggestion we can have a "Global Unique Channel ID" so that
will be possible. A free alternative sounds cool, once we get the file
