<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>
