Pity they don't have any suitable AMD mobo's. Never dealt with them,
and no idea how 'reasonable' their prices or kit are (though it would
be hard for a business to offer cheaper second hand prices.</pre>

Ah, they're over east. I was looking for a suitable local
refurbishing place. Ross and McClerrnons (sp?) auction houses, as
Nick ahs pointed out, seem the clearest options.<br>

I guess if we can't get anything better, maybe we'll have to shell out
some dollars for something. I'll do another request to the plug list
'just because'. I'm a little surprised we can't get a loaner from
someone in PLUG.</pre>

How much grunt do we need for our DVSwitch host for the first few
trials? If it's 'not that much' for simple stuff (and not minding a
few skipped frames etc), maybe the newer of the old boxes *might* do
at a stretch, though it is single core. We'd need a replacement
camera box though.

Well spec on DVSwitch page suggests

So I think we need a dual core system, whre one core will just be
the Theora compression (to send off to icecast). The other core is
the primary video frame grabbing. Indeed, it would be nice if we
were quad core, becuase then we'd have some spare cores to do some
effects on (and have murmur/mumble nicely out the way).<br>

I'll add tonight's rendez-vous at Artifactory to the PLUG calendar
give you guys (Nick and Tim) are confirmed going? Anyone else
available?<br>
