BBC HD is one of the more demanding h264 encodes commonly seen, so maybe not so surprising that it's even more demanding when running at full resolution! Maybe it's too demanding for some set top box decoder chips and this is the real reason they have been running at 1440 all along...
That said it plays fine on my GT430, well no more glitches than any other HD recording anyway :-P
Does look really good on some programmes, the ones that are evidently top quality productions, technically at least.
