I saw great improvements when I was using a single standard def capture card and recording/commflagging/watching all at the same time. I would get frequent pauses until I threw in a 40GB system drive I had laying around. I've since moved far beyond his setup (6 tuners, 2.5TB storage) and would never dream of putting mysql on the same drive as my recordings. I'm even considering moving mysql to its own drive separate from the system to help minimize loss and wear/tear on the drives.</div><div><br></div><div>-Brad</div><div><br></div></body></html>
