I have my Ceton card in my

I have my Ceton card in my main HTPC since I do all my recording there anyway.   I already have my HDHomerun using network bandwidth while recording and sometimes have glitches that might be attributable to networking issues, so why burden my cable card recordings with that as well?  Theoretically gigabit ethernet should be able to handle it, but in practice sometimes it doesn’t work like that, at least for me.

Now, if your cable drop happens to be next to your server rather than your HTPC then I can understand putting the tuner there 😉
