Its not a question of cards/devices, its a question of the number of 
adapters...which is currently set at 8 (see dvbdev.c for the 
max_adapters define). Example, a usb device with dual receivers means 
only 4 such devices would be supported ... if you desire more, change 
the define and recompile the drivers.

Note that "support for x number of adapters" is also somewhat dependant 
on the software you use -- though I'd expect that most would be 
respective of the above, you still should check the application to see 
if it has any further restrictions.

Just keep in mind that when you want to record HD content from the 3 cards,
you have 3 x 20MB/s and mostly this is more then your HardDisk can get :)

That is incorrect.  hdd saturation is not an issue. Examples:

TS for 8-VSB source:  ~19.4Mbps (~2.4MBps)
TS for 64-QAM source: ~27Mbps (~3.4MBps)
TS for 256-QAM source: ~38.8Mbps (~4.8MBps)
....
insert other rates here
....
....
