Perhaps the next generation of DVRs has been released by Neuros Technology called the Neuros OSD. This open source, linux-based, completely hackable device allows you to watch and listen to your media where and when you want to. Powered by
a dual core multi-media processor, OSD can record from any source and
record to a variety of open formats so you can play your content on
various devices from laptops to cell phones.
