Actually no...I output 1080i at 60 from X regardless of the content.
That said, I'm not sure I record any interlaced stations that aren't
1080i. Almost everything I get these days seems to be either 1080i or
720p (in which case no de-interlacing takes place).
I'll have to check out what happens with some of the few SD stations I
get. Even the local PBS stations I get seem to have gone to 1080i
