UberNerdy tip-of-the-day: If you want a super-cheap TV on your Mac OSX computer (along with EPG & PVR) – install Ubuntu Linux on a Virtual Machine (e.g. Parallels/Virtual Box) and install Me TV (link: https://launchpad.net/me-tv/) software (from the Ubuntu software repository) and buy one of these super-cheap DVB-T USB sticks: with https://wiltronics.com.au/product-category/raspberry-pi-usb-dvb-t-tv-tuner-rtl2832ur820t/ and a co-ax adapter like this: https://wiltronics.com.au/product-category/mcx-to-pal-cable-for-rpi5400/
– it works perfectly under Ubuntu 14.04 LTS (DVB-T standard countries only).
It saved me hundreds of dollars after looking for equivalent stuff for a Mac – there is no open source MacOS TV software I could find. In fact, if I had used Virtual Box rather than Parallels, the only cost would’ve been the USB TV tuner. Plus the amazingly cheap USB stick I used is great for Software Defined Radio (SDR) – you can monitor a huge range of frequencies using http://gqrx.dk (directly in MacOS – no need for a Linux VM) – as well as listen to normal radio & emergency frequencies, aeroplanes, maritime radio, satellites etc etc. There’s a fascinating world of radio and data out there!
Naturally, installing a whole VM OS is probably overkill for one application if you’re just after a desktop TV – I use Linux a lot for research purposes, so the best of both worlds. Smaller Linux distros like PuppyLinux might also work.
