Probably not, but I've not got a clue where to start and, as I'm not
using the GUI anyway, it seemed easier to hack the database.

I've no idea - as I said before, hardware isn't really my thing.
They're 2.5GHz Xeons with 2MB cache, that's all I know.

Apologies, looks like I typo'd the model number.  It's a DL740.  As
above, I've no idea about PCI buses, but I can't see 12 x 35MBit Mux's
being a huge problem.

It's an onboard controller, but I'm told it connects via the PCI bus.
The hardware guys here are also telling me the issue is down to the
write cache, so we might have to mount up the video folder from the
attached storage server via NFS.  All the media will end up on it
anyway, but I was planning on keeping thw raw mpeg on local disks and
only dumping the re-coded files down to storage.  If it solves the
problem though, there's plenty of space.

Well, I'll have a 'spare' box with 5 x Nova-T (single tuner versions) in
it as soon as this one is ready, so I may well give it a try.
