    Is something like this possible?
    Code:
    SELECT EWRrio_streams.*,
        FROM EWRrio_streams
        LEFT JOIN EWRcanal_channels ON (
            EWRcanal_channels.service_id = EWRrio_streams.service_id AND
            EWRcanal_channels.channel_value1 = EWRrio_streams.channel_value1 AND
            EWRcanal_channels.channel_value2 = EWRrio_streams.channel_value2
            )
    ORDER BY EWRrio_streams.stream_viewers DESC

    SELECT * FROM table1
    INNER JOIN table2 ON table2.id = table1.id
    LEFT JOIN table3 ON table3.id = table2.id

    i've written an example for you.
