I think I bought the wrong tuner. I purchased a interal/pci Ceton InfiniTV 6 when it was on sale about a month or so ago (cheapest I had seen). My HTPC isn't finished yet so it's still in the box. I was doing more research and found out I can't just assign tuners from the card to other computer, only extenders (part of me knew this but I didn't fully understand).
Anyway, my question is, if I sell this internal card and purchase an external InfiniTV 6 or HDHomeRun Prime, can I assign those extra tuners to other random PCs in my house, or does the external units require extenders as well? I just need viewing ability on the other PCs, not recording, I only need to record on my main HTPC. Also, if I understand correctly, only extenders can watch DVRed content from a main HTPC, even if I use a network tuner instead of an internal, DVRed content is locked to the PC it was recorded on unless I use an extender? Do I have all this straight now?
