CountryBumkin on another threads got me to thinking about this...
BTW - just tried to watch some Live TV on the client machine in the bedroom. Says I have no Tuners available.
I too have been having some problems freeing up TV tuners after use. On several occasions I will see the dreaded "No Tuners Available" message or the MC TSRRender message (meaning "No Tuners Available"). This happens even when only one of my three tuners are actually in use either watching (or recording) a channel. Each time it happens I check my current recordings in use and there is never more than two under way so I should be able to watch a third channel but sometimes can't as the message comes up telling me i have no free tuners.
When I first boot Windows all three tuners are available as I can record three channels at once, watch one & record two, etc. After using MCTV for awhile it seem that the number of tuners is reduced as the error messages start flowing.
I'm beginning to wonder if once a tuner is used it may not (under certain conditions) be completely freed up after use.
I'm also wondering if still having WMC installed in my Win 8.1 system may be a contributing factor?
