Missing from BBC HD

Trawling through my double issue of the Radio Times, I've noticed that the majority of prestige BBC dramas are still not appearing on BBC HD, which I find somewhat disappointing to say the least.
Over the Christmas period the following have all been missing from HD whilst we've been treated to repeats aplently on BBC HD;

• Doctor Who
• Oliver Twist
• Sense & Sensibility
• Ballet Shoes
• The Shadow of the North

I know the Doctor's special effects preclude its HD filming, but you would have thought the others would have been shot in high definition? I find one of the big benefits of HD is the handling of dark n moody backgrounds, the meat and two veg of winter drama, but these shows are all still being shot on film but broadcast in SD. Most odd.
