Yes, I got the same effect here if i connect the loopthrough output of a
Rev.1.3 card with the input of a Rev.2.1 (WinTV nexus s) card. The ARM of
the 2.1 crashes almost immediately, and the 1.3 stays alive, but produce
those (heavy) glitches.  I tested this with vdr1.0.0pre3, but I think it's a
hardware problem related to the different receivers used on that cards.
(missaligned impedances or something...)

I ended up not using the loopthrough, my single LNB-line connected to the
secondary card only, and using the small (but effective) patch from Klaus
introduced in the "help adding another card" thread. This configuration
works perfect for me.
