1 what on earth is this
2 what does it have to do with a ps3
3 what does it have to do with mythtv
4 why is it posted on the mythtv mailing list if it is about a ps3
3. Info about cracking the PS3 would assist in making it an even

better/more useful machine,

4. Ultimately perhaps resulting in a mythfrontend (or an xbmc port, or
something useful!)

The crack gets you three things: access to the 7th SPE which was formerly used to run the hypervisor, access to a few dozen MB of memory formerly used to run the hypervisor, and access to the GPU for OpenGL support.  Just because you can access the GPU doesn't mean OpenGL will magically work, you still need to write drivers for it.  Even were that to happen, the GPU does not provide any sort of hardware decoding, that all has to be done on the CPU.

The removal of the hypervisor frees up a _single_ SPE.  Linux on the PS3 has had access to six of the seven for the last four and a half years.  At current, the best they have managed is partial offload of MPEG2, the equivalent of XvMC.  Everything else must be run on the rather limited in-order PPE.  The extra SPE will provide the system exactly no additional worth as a media player.  Beyond that, the system is painfully low on memory, and will be swapping just to boot into Linux and start up a 1080p frontend.

The PS3 has absolutely no worth as a Linux media player.

In reality isn't this crack likely to result in greater hardware sales for Sony?

Why would Sony care?  Sony subsidizes the price of the hardware to encourage sales.  They take a hit on each unit sold, under the assumption people will be buying lots of games and movies to use on the system.  If you crack the system to run Linux, or homebrew games, or HPC applications, Sony is losing money.  It is in their best interest to keep the system locked down, and keep you using it for their intended purposes.

Sony began making a profit on their console sales almost a year ago
