uint TVBrowseHelper::GetChanId	(	const QString &	channum,
		uint	pref_cardid,

	)			const

Returns a chanid for the channum, or 0 if none is available.

This will prefer a given sourceid first, and then a given card id, but if one or the other can not be satisfied but db_browse_all_tuners is set then it will look to see if the chanid is available on any tuner.
