Advertisements I have a need to record some broadcasts for foreign language educational instruction. So I thought that Tivo would be ideal. Nothing could have been further from the truth. The channel I need to record from Cablevision (TV Japan) cannot even be displayed using Tivo. After a number of calls to support, I learned that this is a limitation of the current cable cards. The Scientific Atlanta DVR box from Cablevision has somewhat less severe problem: you can watch the broadcast but you cannot record it. Shouldn't Tivo and Cablevision present a clear and easily located list of channels that are not compatible with the services and products they're selling? My understanding is that the reason is the use of "switched digital" technology - meaningless jargon to me - by some channels. After considerable time and money I have a box that wouldn't even make a good boat anchor.
