It would be very useful if there was a list of the capabilities of particular DTT boxes. The reason I suggest this is that there are a number of boxes which are incapable of performing all functions. An example is the Samsung SIRU2000i which is unable to handle BBC Interactive and also the 7 Day EPG. These are serious shortcomings and I would not wish to purchase a box which does not support the full range of DTT enhancements. Does anyone know where such information is available in one location, please?
