Make sure in MythTV-setup : General, under the "Job Queue : Host Specific" settings, your "CPU Usage" is set to LOW. The other thing to consider is some form of hardware MPEG, like a PVR-x50 or HDTV card. With 2 PVR-250's and an air2pc card recording at the same time, my Athon1700 backend is running about 15% cpu, even with upwards of 10M/sec being written to disk. Myth 0.17 makes it far easier to have other machines do the commflagging as well, also worth considering. Even something as slow as a P2-500 will do fine when commflag is allowed to use ALL the cpu.
