It shouldn't. We disable local recording on clients. After scheduling a recording (on a client), wait for a few minutes to let the info be sync'ed with the server. If you are unsure, you can do a manual sync on the client. Then go to the server and check if the scheduled recording show up on the server (in To Be Recorded list).
No. It should work as it is. On the server, make sure you go to TV Options... and select each tuner in the list, click Configure... button. On the resulting popup, make sure the Tuner type is OpenCable, and not "Disabled". When MC tries to load a tuner, it actually check to make sure the tuner is not being used by any application anywhere. So if you use one tuner on a client, the server should use the other two available tuners for recording. You will miss recordings only if you scheduled more recordings than you have tuners for. Remember using a tuner on client reduces the number of tuners available for the server.
One important thing you need to make sure about is no other applications are using the tuners anywhere on your network. Windows Media Center is known not to play nice when a tuner is being used in another process.
OK, so what you say makes a lot of sense, and I agree that this is the way it should work...but it doesn't seem to. If I was watching something on my client, and the tuners were in the same priority, then it never looked for a new tuner...
I disabled DLNA on my client PC (effectively disabling my Prime Tuner on the client), and now it doesn't interfere with recordings that are scheduled downstairs...
BUT
I tested this morning by trying to record something from the guide that was playing, as well as scheduling a recording that was starting in 10 minutes...neither started recording...how long should it take to sync with the server?
I also noticed that I can't rename/move files from the client...it says in the dialog that it is invalid under the 'new name'...not sure if that has anything to do with my issues or not.
I have all Windows Firewalls off, and no 3rd party firewalls (except hardware on my router).
I do have some stacked tuners as well (which weren't even available on the client)...again, not sure if that matters, just trying to give a clear picture of my setup.
Sorry it took so long to respond, for some reason, I didn't get a notification on this topic that a reply had been posted.
