But MythTV definitely supports multiple simultaneous recordings. MythTV even supports recording multiple programs from the same multiplex only using one tuner. I've recorded shows from 7.1 and 7.2 at the same time while the other tuner was recording something else. > Also, on the hardware front, what's the maximum number of tuners anyone has > ever had in a single DVR?

I don't know what the max is, and I've never had more than 2 tuners. Recording OTA doesn't require much CPU, and not even a whole lot of disk. I suspect disk would be the first bottleneck with a large number of tuners. My current MythTV box is more powerful than my old one, and it's only an AMD E-450 APU. Recording 2 HD shows simultaneously barely makes a blip in top (10% us, 4% sys). I think external tuners like the HDHomerun use slightly more CPU than the PCI cards I used to have, but not much. But I wouldn't go back to the PCI cards for anything. I love my HDHomerun. My old MythTV box had an issue when starting recordings, but moving the MythTV mysql database to a separate drive fixed that. I know my tiny foxconn box can do 3 simultaneous recordings to a USB 3.0 external drive. If you want to record 4 or 8 simultaneously, SATA and multiple drives might be necessary, but maybe not both. MythTV's storage groups can help ensure simultaneous recordings get spread out to multiple drives.
