ok here is what I found.. from microsofts website..
Approximate amount of disk space that each recording level will consume is:
•
Fair: 1 GB/hour
•
Good: 2 GB/hour
•
Better: 2.5 GB/hour
•
Best: 3 GB/hour
Also the recording is in a different format.. Windows Media player doesnt even play it.. so you can only used it on the center itself.. I hope this is what you were looking for..
