1. TV2 - shows a sitcom Better With You in HD and follows immediately with their highly promoted American Idol in SD! They say hot off the satellite so perhaps they are not willing to pay for a HD version or the bandwidth?
2. TV3 - House in SD (rumoured to be because TV3 doesn't want to pay extra for a HD version).
With the good upscaling going on these days I would almost prefer SD/DD5.1 over HD/AAC
