[mythtv-users] Hauppauge 2250 causes dropped network packets

[Robert Shields]

I have two 220s in my system and haven't noticed this (I have had no visible
LAN issues, so I never had a reason to go looking to deep though).

A good first step is to simply try the card(s) in different
slots...sometimes you get lucky and this clears up the possible conflicts.

If the problem persists, maybe look in your BIOS for a way of setting the
different interrupts or something along those lines.

I am not a huge linux know-it-all so I am not sure where to begin in the
actual OS.
