As stated tonight I decided to see how many channels I could tune at the same time. On the HTPC I am recording three and watching one, and the wife is watching OTA live TV using the TV's built in tuner so we have a total of five OTA channels tuned in and all seem to be tuning in fine. Tomorrow I will check the shows I recorded to see if I have any glitches. Signal strength is 100% and signal quality is 95-98% so all looks good. With Kodi/Media Portal I never could do this. If I ran more than 3 tuners I would start having drop out issues.
