I had a bunch of episodes of Eastenders recorded and when deleting one episode I recorded it went to the next episode delete option and deleted an episode I was about to watch.
However going from a recording to BBC iPlayer I noticed a small upgrade in picture quality.
Just a heads up - I don’t have any pixelation or service issues
Having both Sky and Virgin it does seem that the channels are significantly lower in quality than Sky, are they taking DVB-T feeds off channels like Really and Drama? Only channel that looks better is Talking Pictures TV

What you are seeing is a little trick that is built into the Freeview HD MPEG-4AVC decoder toolkit that samples the incoming bitrate & can vary the output frame by frame between 1080i & 1080p, depending on how the programme being broadcast was encoded. Freeview are the only platform to have decoders that operate this way. Sky & Virgin do not have them.

Up to March 2011 at lot of BBC content was shot in 1080p25 but within a single programme interlaced might be used for moving credits, cross-fades and studio shots. Subsequently the coders for the BBC HD muxes encoded, on a frame by frame basis, progressive frame or interlaced frame. This is why you get a mixture of 1080p and 1080i on Freeview.
