I've talked to several people who state that mythtv is a bit irritating
for live tv surfing and watching. I've read other posts claiming it
takes 5 to 6 seconds to change channels. I would consider it slow.

Hmmm... the CW3000/4000 take about a second from the time the remote
button is pressed until the new channel is displayed. Maybe the ir
code needs reworking ?
Lets not split hairs here... it shouldn't take 3 seconds from the time
you push the remote button until you see the new channel.

You might want to search and read some posts in this group and the
mythtv users group. I don't think those people are random.

I'll be doing just that.

I agree.

I'm fully prepared to do that.
