I would have guessed that the probability for the DVB card to lock up
would be higher if the PIDs _are_ set.
Are you really sure that this change fixes the problem? Here on my box
I don't seem to have any problems with not setting the PIDs.

I believe there's more to this problem than just this. For instance
on a system with only a DXR3 card as primary device the Transfer Mode
also has to be re-launched. I'll need to look further into this before
changing anythig here...
