I'm trying to get a handle on weighing the options for a new ATSC tuner
 card; I've looked looked through the list archives and haven't quite
 found an answer to these questions.  (Perhaps, if they get answered
 here, the answers could find their way into the ATSC_cards page in the
 linuxtv wiki?  Can anyone add stuff to the wiki?  If so, I'd be happy
 to do it.)

The DVICO Fusion HDTV5 Gold, HDTV5 Lite, and Airstar HD5000 all appear
 to work under linux now - fantastic!  But why use one over the other?
 Here are some questions that come to mind:

 o Is a dual-card/dual-tuner setup possible with any of these?
 o Do the linux drivers support recording from analog broadcast?
 o Do the linux drivers support recording from composite/s-video input?
    (I believe only the HDTV5 Gold has such an input, right?)
 o What kind of closed-caption support do these cards have?
 o The HD5000 can do TS stream demultiplexing in hardware, correct?
    What kind of impact does this have on its performance (i.e. what
    kind of difference does this make, and when)?

 o [A non-linux related question, for the heck of it:]
   I believe the RF frontend on all these cards is the same; do these
    three cards work equally well in pulling in an HDTV signal, in 
    multipath rejection, etc?  (How about analog broadcast signals?)

Thanks for any answers/tips/pointers!
