Four, CBBC and CBeebies now downconvert to 576i on their SD outlets. BBC One and Two have been doing this for some time.
CBBC and CBeebies haven't had the HD bug for some time now.
Which begs the question...
BBC THREE's refresh last year before being moved online lacked an HD bug on the DOG
. Was it also down converted to SD (like with FOUR, CBBC, CBeebies), or was it two versions of the channel?
