No IRQ Problems. All cards are on separate interrupts and using Intel
chipset.

I would like to point out the thread: [vdr] Re: Mux A / Channel 5 UK
DVB-TbrokenwithVDR,dvbstream works...
, which sound similar to my problem.

I have tested this aswell on dxr3, where input came from Nova DVB-T. The
DXR3 card show all moving parts OK, but there is this stuttering involved,
where frames are dropped. My CPU idle is about 65 % all the time, so I think
that is not the problem. But i rather would like to use DVB-S card to output
my video anyway and dxr3 does not go along with my topic ;-).

I also did try the fifo method succested by Gregor an can confirm, that the
drivers are working ok.

Does DVB (TR) streams have same characteristics when talkin packet size?
Could it be possible, that packets are 2324 or unconstrained and not 2048?
You do create PS are you not?
