There might be extra keys you can press (or codes for lircd to send) to
improve the speed at which your cable box or satellite receiver changes
channels. With the Scientific- Atlanta Explorer 2100 I'm using, there are
three ways you can go straight to a channel:
1) Enter the digits. This is slowest, as the OSD will pop up, wait a couple
or three seconds before it figures you've finished entering digits,
change the channel, and keep the OSD up for a couple of seconds after
changing the channel.
2) Enter the digits, then press SELECT. This trims off the delay before the
channel change takes effect.
3) Enter the digits, then press SELECT, then press C. This is fastest. In
addition to getting rid of the delay before the channel change, it gets
rid of the OSD after the channel change. There might still be a delay
before video from the new channel actually shows up, but there's an
even bigger delay before an ivtv tuner actually starts recording.
At this point, my MythTV box changes channels on the cable box faster than
my TiVo did. TiVo recordings would show a second of the previous channel
followed by the channel-change OSD. MythTV recordings don't exhibit this
There might be something similar that you can do with other cable boxes or
satellite receivers that will accomplish a similar speedup.
