I just got a new ARRIS cable box that is connected to my HD-PVR. After some period of time, and the box tuned to the same channel TWC sends a message "press any button to continue watching this channel" Then it starts up a screen saver

So the next time the you tune a channel on the HD-PVR the first digit sent by the channel change script wakes up the cable box, then it tunes to what ever the remaining digits are.

If a human makes the change, you can re-enter the channel number an all is cool.

That is until you really want to record something on an HD-PVR channel in the middle of the night end up on some strange channel or you record the screen saver for 2 hours Have used other cable boxes but have never ran into this problem.

Any suggestion on how to deal with this?

hitting the info button every hour would probably keep it from falling asleep. I'm assuming you have gone through the menus and looked for anything that says power saving or data saving something like that?

Yes I've looked through all the menus and the sleep & auto power off, all at the off setting.

I did like the idea of the info button, Maybe just send an OK before the channel information. Thanks for the suggestion. I'll let you know.

Yea, have already been to that setting. It is set to off.

I think you have the right idea with sending a some kind of "code" to the box before sending the channel numbers will do the trick.

I think that sending a KEY_ENTER will answer the stupid "Do you want to continue watching the current channel?" question if it's there, and if not should do anything.

So my plan is to modify the channel change script to send an 'KEY_ENTER' then '"sleep 2" then send the channel code.

Just haven't had time to play with it yet but will let you know how I make out.

Thanks again for the excellent suggestion!

Update:

I made the changes to the channel_change.sh and so far so good.

On the first channel change of the day to the HD-PVR it worked. (In the past this always failed). So am hope full this will be a good solution. The real test will be with a recording so will be testing that next.

What was the change exactly?
I am thinking of adding a pre_channel change process to the script and will use your change as an example.

Here's my current channel change script.

Code:
#!/bin/bash
###################
# channel_change.sh
###################

REMOTE_NAME=blaster
DEVICE=/var/run/lirc/lircd1
SLEEP_TIME="0.2"
STB=0_85

send () {
irsend --device=${DEVICE} SEND_ONCE ${REMOTE_NAME} ${STB}_${1}
sleep ${SLEEP_TIME}
}

send KEY_ENTER
sleep 2

for DIGIT in $(echo ${1} | sed -e 's/./& /g'); do
send KEY_${DIGIT}
done

send KEY_ENTER

#
# If your cable box is slow to change channels, sleep so that Mythtv doesn't
# move forward until after the resolution has changed
#
sleep 3
exit

I added the
Code:
send KEY_ENTER
sleep 2

to my existing script.

My solution is similar, though I am using a Scientific Atlanta box. I send 0 (zero) then send ENTER. This has the effect of doing nothing if the box is tuned to a channel. If the box is "sleeping" then it wakes it up again.

I hadn't thought of that combination but will have to check it out . Sounds like a good idea as well.

For some reason KEY_ENTER is throwing an error in my _lircd-0.9.2a.log file.
Code:
Oct 20 16:35:23 mythtv2 lircd-0.9.2a[2537]: Error: error processing command: SEND_ONCE blaster 0_85_KEY_ENTER
Oct 20 16:35:23 mythtv2 lircd-0.9.2a[2537]: Error: unknown command: "0_85_KEY_ENTER"


The question is what can I send that works?

I've only noticed this since the R8.4 upgrade but may have been doing this longer.

The question is what can I send that will do the same thing and work?
