Even though things seem to be working better for you, I thought a little extra
info might be helpful:
(1) DCT2000's are frustrating beasts. If you send the keypresses too fast, it
doesn't get all of them. If you send them too slowly, it times out between
keypresses. It gets to be a matter of finding the "just right" delay between
keypresses. Hopefully the script that you found will do that.
(2) The timing method in the script can be very important. A few years ago I
found that I was constantly getting the same Tuesday night recording messed
up. My tuner would go to channel 6 and get Leno instead of 26 for Inuyasha.
All other channel changes worked perfectly. I searched around in the logs,
and found the events for each keypress. There was a 5-7 second delay between
the 2 and the 6, and my DCT2000 would time out. I had a rather low powered
backend that was doing some other task every Tuesday night, and thus there
were big delays during my channel change. After that, I called nice to
increase the priority of my channel change script and everything has worked
very well since then.
