Want to use multiple authorised Viaccess cards.(DVB S)

However the reciever seems to like only Red Viaccess 2 Cams (scm)

It does not like :
1: Viaccess extra (NP4) (In non Mpeg 4 mode)
2:Zeta Cam

Questions
Will 2-3 official cards all work in 3 Red Viaccess Cams? ( some recievers seem to get confused and are unreliable at handling multiple Similar Cams)

Are there any Viaccess Cam variants that may work, especially if they could take two cards?

How easy is it as a novice to change the Card Reader to Viaccess? ( If so a link much appreciated)

Many thanks, the dealer telling me that it will record in Mpeg, frankly i did not believe.
Thanks for the confirmation, its a pain, but understand.

thank you for very quick response.even more interested in this reciever!

However just so i fully understand your response, bearing in mind i am a relatively new to sat broadcasts:

2-depends on service viewed
So if
A: non HD service FTA can you record in Mpeg 2?
B: non HD service encrpyted but with correct viewing card can you record in Mpeg 2
C: If Hd transmission encrpyted assume it will record in mpeg 4?

3-yes, you can watch SD and/or HD services
Assume this means that "out of the box" the two installed DVB S2 tuners will also decode standard DVB S transmissions, assuming FTA etc?

Have tried without success to verify what the Uk distributor is telling me....
Namely
1: DVD Writer can be added later? is this true, or purely a DVD Reader ? ( slimline version)

2: Out of the box, this unit will record in mpeg (2 or 4?) as alternative to "raw data stream"?

3: It comes with two DVB S2 tuners. Does this mean these two tuners will also let you watch standard Digital DVB S channels. ( ie: non HD channels=FTA)
( Understand you can add extra 2 DVB S tuners later if required)

Thanks for your patience, but new to Dream and keen to join the club!
