Another entry into the field of personal video recorders, this one from TerraTec. This one differs a bit from TiVo and ReplayTV, though, in that instead of being just one box, it’s actually modular. The LANcaster has three separate parts – a TV tuner, a storage module, and an interface module – which can be joined together over Ethernet connections. The advantage here is that you can easily add extra storage space, something that’s a pain to do (and warranty-voiding) with a TiVo or a ReplayTV, and put interface modules in different parts of the house to be used with other televisions.
