By ‘losing power’ you mean it switches off? Or does it brown out?
Do you run all your incoming current through a proper UPS system, or at the very least electrical filters to stabilise the fluctuations in the electrical supply?
Are there any large switching devices on the same circuit as your sensitive equipment? (i.e. ovens, large motors etc)

Thanks Kaspar and Luke
Lots of good info and plenty to think about there.
We can actually play back 1080i50 footage on the humble dual 1.42 G4 with our current RAID, so with the faster machine we should be fine.
My first thought was to avoid having the telecine run to tape and instead ask for the footage to be saved directly to a portable hard drive, with a tape as a safety. We would have to confirm with the telecine house that they could provide the codecs we require.
We won’t be keying anything, so we could reasonably stick with 4:2:2 1080i50 which would finally be downconverted to an SD master. In the future, if we move up to 4:4:4 we’ll have to get the top of the range BM card and a new RAID anyway.
A couple of extra thoughts:
Our X-Raid will be fully populated and already has 2×512 caches, however it was striped under Disk Utility in 10.3. I seem to recall reading somewhere that stripes performed under 10.3 will perform 10% slower under 10.4 and that a restripe is in order. Any confirmation on this?
What is the current situation with Apple’s undocumented gamma corrections when coming to and from their uncompressed codecs?

I don’t know why but that post got titled strangely when I submitted it.
The original title was ’35mm And HD Workflows’ which sounds much more exciting.
And .. we can’t edit our posts?

If you need to do so, here’s the hint:
