Looking through the source of the sa3250ch, the -s option send the
channel as one number '253'. The default is the send the channel as
three numbers '2', '5', '3'. Neither path allows for 4 digits. I've
played with the default path to encode 4 digits into the avc1394 cmd,
but it doesn't work. I admit to not lookup the avc1394 api calls.
