My Tv asked for a channel update a few days ago and I noticed that BBC4-HD disappeared from the list immediately after. Then I noticed MotorsTV was missing. I did a manual signal scan and discovered that CH33 (570MHz) is pretty much dead on this TV.
Oddly - the PVR box hooked up to the same connection (from same loft box output) is happily receiving those channels from its previous tuning config.
So either my TV has developed a blackspot for CH33 or the channel info is not being signalled correctly in whatever overheads the TV is using to find a signal - anybody else with some funnies on CH33 ?

No it was just me - swapped ports on the loft box - no difference.
Swapped out factory made link cable from PVR to TV and hey presto all good - never seen a cable fail with such unique effect on one channel.

What multiplex is Motors TV transmitted on?
Is there a website which explains how the streaming channels work?
