<div>I have three HD-PVRs on my system running .26 Mythtv. I have set udev rules up to tie down the devices to keep them from shifting on me. I use a commandir with just using the command line interface commands to change my channels.</div>
<div> </div>
<div>The commandir scripts, which I have three of them, are set as follows:</div>
<div> </div>
<div>
<div>for video0 - I don't have a sleep command before the channel change. </div>
<div>for video1 - A 8 second sleep command before the channel change. </div>
<div>for video2 - A 16 second sleep command before the channel change. </div>
<div>
<div>
<div> </div>
<div>The sleep command is used to prevent the three scripts from colliding with each other if 3 shows start at the same time. </div>
<div> </div>
<div>My problem is this will work fine for most of the time. But then I get channels not changing properly on a couple of the HD-PVRs. It seems to jump around a bit at random and then return to normal. I can watch each tuner and change channels without any problems. </div>
<div> </div>
<div>I was wondering if anyone had any thoughts. I wouldn't think the MythTV system getting channel lock on the channel would matter but could that be affecting it? </div>
<div> </div>
<div>This does seem to happen more at night and my system is relatively new so it is recording often catching old shows. Could I just need to increase the sleep counts?</div>
<div> </div>
<div>I also don't have a pretune channel set. Just the starting channel is set.</div>
<div> </div>
<div>Thank you for any input.</div>

I still occasionally have problems with 3 digit channels (for example, last weekend intended channel 162 recorded channel 12 instead) so I'm still tweaking the delays. The only thing that might improve it is if it supported the native CommandIR settransmitters-#, since CommandIR claims that's more reliable than the irsend's SET_TRANSMITTERS (I could hack the script for that I suppose...)<br>
