I think you have nailed it. Recordings from BBC-HD are fluent now. Will 
test live TV later today (at the moment they seem not to broadcast BBC-HD)

playback of recordings from film1-HD has also improved.

HD-NL recordings with EXQI branding on left hand side are still not OK. 
Its as if i get dropped frames.

Very good improvement!
