544x576 = 0.94:1, or should it be 576x544? which = 1.06:1.. still making not much sense to me.

As you may remember my VM DTV experience was atrocious which is why I now have Sky+.

Using Dave as an example, from what I remember as I almost never bother to watch it, the PQ between Freeview and Sky is pretty much identical. Back when I had VM DTV the PQ on Dave (or as it was UKTV Gold2) was below that of Freeview, like watching a mpeg4 movie from poor filmstock and with a bitrate below 800. Not unwatchable but with grain and unnatural contrast levels and colours.

As a matter of interest how does one find out the actual bit rate and the resolution of broadcasted material. All my assumptions are just based on perception.
