There's a lot of debate on the practical use of DVI, as well as DVI vs firewire. Some say DVI is non-sense while other say that you get better quality with DVI input for digital displays.
If DVI becomes a standard, I would want my RPTV to have this option.
A DVI connector is for viewing digital programming; to record a digital program in a digital format, users will also need what is known as an IEEE 1394, or FireWire, plug to connect the TV and the recorder.
The digital FireWire connection will allow program providers to restrict the number of times that a program can be recorded. Under the agreement, HDTV programs from network broadcasters sent through cable or satellite companies will be completely unrestricted and recordable. Subscribers to pay services like HBO could be restricted from making more than one copy of programs from those services.
While the agreement allows program providers to prevent any recording of pay-per-view or video-on-demand programs, users of hard-disk-based recorders like TiVo would be allowed to record and then watch such a program up to 90 minutes later.
