I watch a lot SD quality TV/recordings and it looks great to me. I'm pretty picky about that kind of thing too. I'll have to try some 1080i video and see if I can tell anything about that. The HD stuff that gets recorded is 720p so I don't think deinterlacing would be in effect then, right?
There was a tweak to the MMAL Advanced algorithm which cleaned it up quite a lot a little while ago, improving SD deinterlacing a lot. If you overclock a little you can also use MMAL Advanced on 1080i stuff with the latest builds instead of being limited to MMAL Bob.
How much do I have to overclock? I don't currently do that and my CPU runs a little over 51C as it is. Here is some sample output of bcmstat.sh watching an SD program:
