I've not had time to check that many channels but I can't see that much improvement in quality, if any. TV One late news on Monday night looked rubbish - much worse than before. Smeary, composite desaturated pictures.
Whether this is TVNZ, SKY or TCL - who knows?
Also Flight of the Conchords on Prime still looks like a bittorrent.
Setup: s-video from a TCL digitial STB into a Pioneer HDD-DVD recorder, component out to a 32" Sony CRT.
