If you are not using 75% of your OS hard drive then install the software on it, else on a spare drive. If the data goes over 75% in any of the hard drive, I would recommend you to install another hard drive or take compression backups every now and then.

So far so good

To avoid many editing problems you should be capturing and rendering your video on a completely separate drive (particularly if you use EIDE drives). Note that simply partitioning one drive into two "volumes" is not a solution either.

The reason for this is that even when you're computer is doing "nothing", other programs may access the OS drive from time to time. This can cause speed fluctuations in data read/write speeds, resulting in artifacts in your captured/rendered video. This is because decent capture/render needs a *constant* data rate.

There's not really any excuse for not having a second hard drive these days as you can pick up 120 gig drives for under $100.

Yes, your OS and apps should share the same drive. The only thing on your second drive should be your media files (and other files associated with your editing projects).

You should also make sure your OS/Apps drive has a bit of spare space too, probably at least 500 meg.
