I suppose I'm not the only one to have recently bought a new AV amp, only to find (through nobody's fault but my own) that it does not have a Dolby ProLogic 2 decoder. There must also be many home cinema nuts around who have a perfectly good amp with Dolby Digital and DTS, but no DPL 2. My Question. Is there a black box available that will decode DPL2 for use with amps that don't have this possibility? Could be a large market out there.
