No. This sounds very much like a cable or firewire port problem.
J30’s have caused us the odd problem and that turned out to be that switching off on the front panel doesn’t power done the firewire interface. Each time we’ve had problems the only way around was to remove the power lead briefly.
In your case though it sounds more like an intermittent cable.

There will always be a difference in quality between what you see on a TV screen played from a DVD player and a software only plater such as PowerDVD.
There are several reasons for this. The hardware-based DVD player is playing out the DVD recording to its native viewing device using the same TV standard, frame rate and interlace. The hardware decoding built into the DVD player also takes into account motion between frames and helps to smooth out any motion artifacts that would normally be visible.
In a software-based player the CPU is having to decode the DVD material and interpret it as best it can. The speed of processing required doesn’t always allow for motion artifacts to be smoothed as well as can be done in hardware.
Also bear in mind that the refresh rate of your monitor is not only not the same as the TV standard that was recorded on the DVD but also the computer display is a progressive scan whereas the DVD is playing back based on an interlaced scan. And on top of that, the displayed picture is rarely the same size as would be shown on the TV.
All-in-all remember that the TV is the only device you can rely on to see what your final production will look like.

12-mins at DV (assuming you’re using DV) would require around 2.5GB at full resolution. ie. DV25. You will need at least double this amount of space for the application to work comfortably with all the temporary files it creates.
If the error is occuring during the render process then there could be a corrupt clip, either audio or video. If you are using any additional plug-ins for effects, these may also cause problems.
The best way to find the problem is to break down the sequence in half then half again to see if it renders correctly. This way you’ll be able to isolate the errant clip.
Most problems when encoding are a result of errors caused by the codecs in use on your machine but in this case as you cannot complete a full render it is likely the problem lies within a clip.

As Matte says, most of the projectors available, Broadcast included, run at a colour temperature of around 9K wheras your studio lights will be around 3.2K. Adding a half or full orange filter will balance the light but you’ll lose some light in the process.

If you’re seeing blue, the camera isn’t receiving any video. Check to see that you’re outputting your timeline correctly for DV playback and that your DV palyback options are set.

For starters, I would close iTunes.
Do you have any antivirus software running and in particular realtime scanning?

That was my understanding of the situation Mike, Unlike After Effects, which grabs the lot whether it needs it or not. This is largely down to the programmer who can set the priority of the running threads.

It could be something as simple as the MPEG1 codec not being installed on your main machine.
As a quick get around, you could try Blaze Media Pro to do the conversion from the Premier AVI file, it’s free for a limited period too.
BlazeMP can be downloaded here.

The SCSI drives can be internal or external but due to the heat created by a raided SCSI array it is best to use the external option in a proper (cooled) raid box. This will also mean your drives are portable and can be locked away sefely at night.

Have your engineers also routed VTR control between the decks and your NewsCutter? Was the SP machine under VTR control from NewsCutter before the changes?
