After advice from 3 different tech guys on the phone I finally got one who talked me through how to solve the problem So the fault is fixable it's just getting the right agent to talk you through it
Hi David,
Thanks for your reply but as my system worked okay with the old Tivo and predecessor it has to be a problem with the 360 box.
Virgin do not want to know.!
Hi
I always try to sync to a live broadcast like the news, you can nearly get the presenter in sync but if they show a video interview on the program the sound will be out of sync on the video, I know there can be technical reasons for this but quite often it is a long way out. Like you I never had a problem with the Tivo V6, also I like the way they tried to deflect the problem to your sound bar which was ok before the 360.
Hi Roy
Thanks for your input.
I agree about synchronising to a live broadcast e.g. the news presenter. Problem is that I can sync it various ways but all drift after a few minutes.
Cheers
I have just switched to 360 today and all virgin channels are out of sync
Audio delay only works one way is there any way to add minus delay
No issues with sync using apps like netflix
Update not all channels suffer the same level of delay bbc being the best
ultra HD channel is the worst total unwatchable as sync so bad
I worked for a vendor to TV companies all over the world. The technical standards people (in the UK ofcom) would be all over that. I delivered numerous updates to the video playback servers to address the precise audio video sync issues.
Interestingly if the sound leads the video by up to about 10 frames most people won't notice as much; as when the sound lags the video by about 4 frames.
Broadcasters have test media with a 1 frame flash and sound pulse every 10 seconds for 1 hour to verify sync and drift.
I regularly watch Hallie Jackson on MSNBC now, VM channel 614. The audio on that channel is usually out of sync, In TV there's an expression It was alright leaving us and I can imagine the signal leaving NBC at 30 Rockefeller Plaza, New York is right. I Imagine the signal is delivered to Virgin by some low cost IP transport route and something in that chain causes the audio to drift in the coding/decoding processes. I'd complain but honestly life is too short.
If you are interested in verifying the sync the youtube APP might be a useful place to go select one of these videos and see if the problem presents
