Advertisements They just dont think that software is important enough. Current so-called PVRs are like having 10 Ghz triple core pentium 5 or Athlons, but running DOS 1. There is so much they COULD do, but cannot due to software limitations. A TiVo is like a pentium 3 running Xp or a G4 running OS X at 2 ghz. The other dvr companies hardware is fantastic but their software is not so good. A bit like having a GT40 that breaks down every hour, and is too wide for our roads. Financial and commercial companies will pay millions of pounds for software, which usually costs hundreds of thousands of pounds to develop. I guess DVR companies dont want to spend that kind of money on software development as hardware is cheaper and the consumer isnt smart enough to realise how important the software is. They probably do not think that people will pay extra for better software. As a concept it is difficult to explain. Hardware is much easier - i.e. dual tuners, smaller size box. Ease of use and ergonomics is also difficult to sell. The Treo and Blackberry smartphones may not have the best specs, but their ease of use and ergonomic factors mean that they have legions of devotees like the Tivo. However all that hardware is fairly useless without reliable good quality software that makes the product easy to use and maintain. TiVo also hold a number of patents so other companies will have to pay them or spend a lot of money developing software.
