To bottom-line this thread: An "1GHz EPIA-M with a PVR-150" should easily be able to watch live TV because... - the PVR-150 is H/W encoding to MPEG-2 - a MythTV process is writing that encoded stream to disk - another process is pushing the encodes stream from disk to the Unichrome MPEG-2 decoder. - the Unichrome driver is pumping the decoded data to the video card.
