Interesting little bug - Using the E. Mids Custom region, a spare Channel 4 +1 channel (Chid 1672) appears at channel 982 in the BBC RB section. I've not tried all regions but a couple of others don't have the channel. I suspect it's an error in the tables rather than an ABM bug

It's not a problem for me but may be for people importing IPTV streams of other BBC RB into that section

Code:
Channel 4+1	1:0:1:2f1c:7ef:2:11a0000:0:0:0:	Channel 4+1	982	1672	0	BSkyB	<channel id="Channel 4+1">1:0:1:2f1c:7ef:2:11a0000:0:0:0:</channel> <!-- Channel 4+1 -->
