In my case it more or less only happens on one MUX, itīs also the MUX with the highest bitrate channels.<br>Also it more ore less always fail while recording "the wire", or some desired show and alway works for test stuff I schedule to test stability.

<div>Hi Henrik,
<div><br></div>
<div>I have a sneaking suspicion that the problem is related to either
reception or the content that is being passed down on a particular channel
at a particular time. I've noticed that attempting to record some of
the same shows each week cause the card to disconnect (on one of my
favourite shows too.. grrr). </div>
<div><br></div>
<div>This is totally unproven, but I have a suspicion that it's
related.</div>
