Recording 11 TV channels simultaneously

Why bother creating an HTPC that can record 11 TV channels? If you're a company that creates PVR software... why not!?

The creators of Beyond TV, SnapStream, have made a few beefy HTPCs in the past, but they've topped them all with their latest effort. It's not the smallest, it's not the quietest, but it sure is powerful, and probably the most featureful HTPC ever, if TV's your thing, anyway.

Using Beyond TV 4, the SnapStream team put together the Godzilla PVR, a system that can record four HDTV channels seven SDTV channels simultaneously. Not bad, eh? So what went into such a system?

Godzilla PVR

That's three dual tuner PCI cards, four USB tuners, and not pictured is a PCIe Theatre 550 based card. They had a bit of trouble getting such a killer system together, however. It was a tight squeeze, and the CPU wasn't too happy with so much transcoding going on (DivX, of course), but a new heatsink fixed that.

Some of you have probably decided to embark on a mission to produce a similar system. But first you might want to consider how much it will set you back. You're looking at over $4000. It's a killer system that can record far more than there is worth recording on the airwaves, though, and for that we takes our hats off to SnapStream.

Check out the SnapStream blog for details on the build.

Anyone know needs to record 11 channels seriously needs to reconsider their lifestyle!!!
That guy is a bit nutz.
He/they need to record so much TV because they spend all the time that they should be watching it… building systems to record it so they can get a chance to watch what they missed whilst doing so.

Daft twats.
not particularly impressed. this seems like an exercise in building the most expensive machine possible, not in a practical solution.

beyondtv might not have a theoretical limit to the number of tuners it can use (most non-xpmce apps don't), but there are little things like the laws of physics - four HDTV streams is about 40mbit of data to stream to disk, seven analog tuners means seven concurrent transcode jobs….. it's not practical, and it's certainly too noisy for the living room. and in the end, what use is 11 tuners in a single box?

far more useful would be some kind of solution where the big noisy tv-encoder box sits in a wardrobe somewhere, and small epia-based boxes could be elsewhere in the box, making use of any number of those tuners through the network. wouldn't that be neat…

Wouldn't it be nice if VLC could capture from BDA.
