[mythtv-users] Need hardware advice for DVB-S HD

[johan]

I have been running Mythtv for sometime, using a DVB-S (nexus-s) card
and a PVR500. After some initial problems to get my CAM/smartcard combo
to work everything worked just fine. 

The cable signals were really poor on the PVR500 (lots of interference,
have a strong terrestrial transmitter very close, transmitting DVB-T and
analogue in the same frequency range)
My DVB-S card has two CAM slots, so I decided to get a second
CAM/smartcard for a second provider, which would decode a second set of
channels. (duplicating my poor cable channels)

Each of channelsets worked fine in isolation (only one smartcard
inserted) but in combination they seemed to confuse MythTV. I could not
switch between channelsets, without being told that I had no
subscription.

I have switched to VDR, which did not give me this problem. (I wish I
could have debugged the problem, but I lack the time and the
understanding of the code, and did not want to raise a ticket for
something that probably only affected me)

VDR does not meet my requirements (that is a personal preference, not
worth a discussion) and I am looking at possibilities to switch back to
MythTV. 
Part of that is to ditch my nexus-s and get new receiver cards.

What I want to achieve is to receive two channelsets, both with the use
of a CI/CAM/smartcard, in HD, with the possibility to use multirec. 
By multirec I mean that I would like to be able to view/record multiple
channels from the multiplex the receiver card is tuned to (probably
unnecessary to explain, but just in case I am using the wrong term). My
CAM/smartcards are supporting this (tested). 

Is anyone running a configuration like this, or can someone recommend a
supported configuration?

For the paranoid, my subscriptions are official and paid for..  :-)
