Hi,
I've got 2 x Nebula DigiTV PCI cards (NXT6000) in my MythTV
0.18.1-r2/Gentoo box and I can't get both of them to work happily.
The first card *always* works flawlessly. The 2nd sometimes works, but
hardly ever. The problem appears to be with the DVB frontend driver for
the NXT6000.
In most cases the frontend driver for the 2nd card loads correctly at
boot time, but dies for some reason shortly afterwards.
This is driving me nuts and I'd love to hear from anyone else that has
had a similar issue, whether they managed to solve it or not! If there
is no solution I'd like to know so I can ditch the Nebulas and get
something different.
There is some output of events below. If any other OS output would be
useful please let me know and I'll gladly post it.
I've found one post from someone else having the same issue, and he
describes it very well indeed. I'm sure his problems are the same as
mine, but he's got 3 cards instead of 2:

The driver for the Nebulas is compiled into my kernel
(2.6.11-gentoo-r6), is there anything to be gained by loading the
modules seperately?
Thanks in advance!
Matt
