The plot thickens. I've done some more tests. I used hdvb to record
samples of BBC 1 HD, ITV1 HD and Channel 4 HD. MPlayer can play all of
them. It tells me BBC is 1440x1088, the others are 1920x1088. All appear
to be interlaced.

BBC appears fine on my HTPC/TV, with sxfe configured for vdpau with bob
deinterlacing. On a remote PC running sxfe (onboard Intel graphics, so
no vdpau) I could see interlacing artifacts, probably because I
configured deinterlacing off in VDR's OSD (see below).

ITV plays too slowly in sxfe on the HTPC. The graphics card is only an
8200 so I tried reconfiguring .xine/config_xineliboutput to use xv and
turned off deinterlacing (see above). It didn't seem to make any
difference, but the CPU is a 2.4GHz Athlon x2, so it should be fast
enough. It was with MPlayer, and so was the other PC (a somewhat faster
Core i5 2500k) with vdr-sxfe.

Channel 4 won't play at all in sxfe on either PC, but does in MPlayer.
