Are you using the box on a USB1.1 port? When running on a USB1.1 port the 
pid filter is activate, ie. eg. when scanning it can take a while until a 
buffer is filled to be returned to the host-PC.

I use the box for almost one year now daily with VDR but on a USB2.0 port.

I'm also using the remote daily. It is a bit clumsy, but it works.

I don't think so. Is it also a problem when you want to watch a channel 
which from a channels.conf which was created by the PCI card? If so, could 
you run femon while VDR is working with the Box and see if the card has a 
lock.

best regards,
Patrick.
