I've been researching Home Theater Recievers since mid December. Early on I'd read some information about the necessity of the Audio Sync/Delay function of modern recievers. Some have said the differences between the Reciever playing the audio and modern HDTVs decoding the signal can be upwards of 110 milliseconds (considerable). I've mentioned this a number of times to salesman and always get the same answer, 'never heard of that being a problem' or 'I've never seen that in practice'. The other day one salesman was able to offer a reason why so many salesman have not had and issue with this. He'd suggested that most signals (in our area anyway) rely on an external decoder vs the televisions decoder. This makes sense but is it true? That being the case how important is the SyncDelay function?
