[mythtv-users] FF and REW lockups with PVR-350

All,

I am experiencing the issues described in the list archives:

  http://www.gossamer-threads.com/lists/ivtv/devel/19002?nohighlight=1

Recently I built a box just to use for MythTV.  It has the following 
hardware:

 ABIT IS7-V2 motherboard
 Hauppauge PVR-350 using the mpeg video out option
 Pentium IV 3.0 processor
 512mb of ram

The Myth install is the latest Knoppmyth release and I have been very 
happy with it except for two things.

The freezes when hitting the FF or REW button really fast several times 
and when I turn on hyper threading it freezes after only a few minutes 
of displaying video. 

Reading the above thread it seems the hardware decoder that Hauppauge 
puts on these cards is rather whimpie.   What I would like to know if 
anyone has a workaround?  Is there anyway to throttle the throughput or 
some other hack other than just being sure to not be too aggressive 
hitting the buttons?  I know there must be lots of setups hitting this 
problem.

I would be interested to know of a motherboard/processor combo that does 
not have this problem as well.  I have a X86_64 box running Suse, but I 
use that for work and would rather keep it that way, but if it would be 
more stable than the new P4 box I may switch them around.
