[all variants] LVM multi raid setup?

view story

http://ubuntuforums.org – I know Linux has great capabilities over the years of using it but I can't seem to find an exact name or setup for this scenario. I want to do Matrix RAID (that is not the correct general name but it was as close as I got) on two HDD. I want to put the OS in RAID 1 for redundancy and then have another partition or folder as RAID 0 for TV recordings both on two HDD. BIOS RAID won't support this and I don't want to get a $150 RAID card so I want Linux to do a software RAID using LVM and/or something I don't know about. (Hardware)
