SageTV limit on the no. of SD & HDTV tuners it can control/schedule?

[mkerdman]

What is the SageTV limit on the number of tuners it is designed to properly control and schedule conflict-free on a single PC?

Is the limit different for the:

(1) PVR-150 SD cards
(2) the Fusion HDTV cards
(3) the R5000-HD HDTV set-top boxes
(4) combinations of each of the above


Thanks in advance.

There is no limit that SageTV places on the number of tuners; it all comes down to how many your system can handle.

How "reasonable" would it be to expect smooth "glitch-free" operation from (4) R5000-HD devices AND (4) PVR-150 cards in a P4- 2.4 Mghtz PC with 1 or 2 GB of memory?

Would lessening that to (2) PVR-150 cards make any difference?

Murray,

I've not run that many PVR devices in a single machine, so not sure what they use up in terms of resources. You could always look at the PVR500's if you wanted, since they are dual PVR150's on a single card. There has been some issues with some people's PVR500's though.

4 R5000's on that machine with 2GB of ram would probably use up about 15-20% of the CPU and have plenty of RAM left over. David ran 4 on his setup which was under 2Ghz, and had plenty of CPU left (dont remember the details, he can tell you though).

Another thing to consider is that you can have multiple server's if you want to spread the load. You just setup one server as an encoding server, and tell the primary server to discover network encoders, and the primary server will control it all.

Multiple servers also eliminates the 4 R5000 limit in the software, as you can have multiple servers with 4 r5000's on each. And then there is Anders' Universal Network Encoder (which works for anything that you can create a DS filter graph for I guess) and Stealth1971's HDNE which can be used for HD OTA cards running as a network encoder. Basically the sky is the limit.
