Maybe I've just been paying attention to the low quality of the SD broadcast more now, since I know that I've got some settings that can be fiddled. I was yesterday trying to change between the XBMC and TV tuner and in both cases the picture seems equally bad. I think I just haven't been paying attention to the quality before. There's a lot more contrast and saturation when watching through TV tuner, but by playing around with the settings I can get the colours I want when watching TV using the XBMC box. I'm sure the settings are as you mention and I've made them default for all channels. I'll post a log tonight for completeness sake, as you say.
