<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>
