Yes, the number of virtual tuners is irrelevant in a properly-configured 
MythTV system (i.e. with all virtual tuners for each physical tuner 
grouped together).  It's only with the "prioritize Live TV over 
recordings" hack that you really need to have a large number of virtual 
tuners to start with before going back and adding one more.

Since your best bet is to no use the "prioritize Live TV over 
recordings" hack--since you want the HDHR on OTA used for Live TV and, 
primarily, only for Live TV--you can use any number of virtual tuners.
