We're in a position at work where we're upgrading a couple of G5 systems to Mac Pros. So we'll have these G5s lying around and I was looking for their best use. The first thing that my mind shot to was Video Satellite LE. I thought the G5 would be an easy host for such a task. But Avid specifies a Mac Pro, so no dice on that.
I remembered long ago eyeing VirtualVTR. It looks like much hasn't changed on their page, I don't know if that's because they were revolutionary and way ahead of their time or because they haven't updated in ages. Anyone have experience with it? I have to take a closer look, but I'm assuming that it acts just like any other 9-pin controlled device within ProTools.
With no ability to playback HD concurrently with Pro Tools, HD playback would be really nice (It's a small disappointment to some clients). But perhaps you have a better idea as to how to repurpose an aging, but otherwise perfectly usable computer...
