As per Simon Rumble I found the PS3 to have a reasonable good UPnP client too. Although the PS3 wouldn’t play back recordings that had obivously had some modifications done. ie. cutlist changes etc.
Once the recording goes into nuv format, the PS3 won’t have a chance in hell to play it. I did some tinkering and managed to setup a custom job to honour the cutlist and maintain the mpg file format. However once the 2nd install of the configuration this failed to work. 1st time I did it on a setup it worked fine. I never did get around to working it out, maybe I might again in due time.
I just noticed that the HDHomeRun units are now available in Australia. HDHomeRun is a dual DVBT tuner that connects onto your ethernet and of course MythTv can then be configured to use the unit, or multiple units. Other software on other operating systems also support it. ie. EyeTV on MacOS X etc.
Having just seen these units now available, I am pretty keen to pick up one in the near future. I have a bit of funds to use on computer items, so I think I will get one once the funds in question are available for my use again.
Of course this means setting up a virtual machine to run mythtv is very possible, as the tuner is accessed via ethernet, so no fancy pci or usb hardware to consider under the guest itself.
