Yes Myth supports multiple virtual tuners - in the backend setup, Go to
Capture cards, for a DVB-T, select Recording Options, and set Max Recordings
here. If you set it to 5 you'll set 5 tuners in the System Status/ Tuner
Status.

Someone else was talking to me about doing something similar on a 
Windows box (ie multiple virtual tuners).  Is this possible for 
FreeviewHD say on a Hauppauge T 500?  Would be cool if I could split my 
tuners again.  Also how many muxes are there on the Terrestrial 
broadcast?  Is there a howto somewhere?
