I'm using Windows 7 WMC to record TWC HD TV. I'm concerned about preserving the copy protected shows & if they are still watchable after a conversion from a basic disk to a dynamic disk in order to setup a mirror (RAID 1). Or, would an alternative type of software RAID be a better choice for HTPC's? Other than preserving the shows, I'm mostly concerned about recovery time from a bad disk when using RAID. With a mirror there's no down time or slow down.
