I''ve tried several way to but the recordings folder (and/or TimeShift) to a mapped drive (z: mapped to \\zeus\tvrec) and a UNC (\\zeus\tvrec) location, but none of them work; if i change it back to the C: drive it works great; Getting error: No Audio/Video Detected.

I want to test things out if the speed is enough. Because the server \\zeus\ had a 8xRaptor 74Gb in Raid5 config.
