Ah - sorry - I thought you were referring to using the cable box's guide
over the capture card, which I thought was a pretty silly idea.
50-100ms is pretty good - I think I'm looking at probably closer to
250-500 ms on my digital cable box.
The satellite receiver I had before that was much much much worse (worse
than Myth by a large margin) which "cured" me of channel surfing.
Myth used to be quite bad for channel surfing lag, but I think it's in the
half second ballpark for me now with livetv (again, not that I do it.)
What version are you running?

Ah - I don't even have channel-up/channel-down mapped on my remote, so
maybe I'm being shielded because I'm actually punching in channel numbers
when I flip back and forth from channel to channel (usually when I've only
got one tuner available, but I want to watch two games at the same time.)

I think if you go back to the very start of that 27 year period, you'll
find that remote controls were not in common use. I'm 32, and I remember
the first time I saw a remote control - and it was connected with a wire.
Just a nitpick, I'm sure you don't remember a time without remotes. ;)

Digital? I think digital tuners tend to be a lot more laggy than analog,
at least from my experiences. It was extremely offputting when I first
got satellite TV back in 199<mumble> (don't remember) but I eventually
"got used to it." Myth wasn't a step back for me in that regard, since I
still had satellite when I first set up Myth.
It'll never be as fast as tuning a channel on a TV though.
