Sat9182,
I tried viewing a DVS broadcast with Smartersplayer on iPhone and used catch-up to watch “The Asphalt Jungle” which provides more details about which exact audio track has this DVS embedded directly into it: it says audio track #2, Whereas BuzzTV v5.0.919 on a 4500 says it’s directly embedded into track #1 only.
I don’t think disabling audio: DTS, Dolby surround sound or SAP or text-to-speech or flipping language supports will help due to its hard embedded singular track nature.
Did not try VLC on a laptop as you suggested which probably means what ever you were watching did NOT have any DVS natively embedded into it from the source, so I doubt using VLC will help.
But it’s been suggested that if it’s hard embedded into a singular audio track then it can NEVER be filtered out or disabled, which is very important to know moving forward.
Can your server filter out these DVS singular audio track LIVE only channels from our service and thus not appear in the guide?
I believe DVS is offered as a free national service for visually impaired but I’m seeing it affecting mostly live TV news broadcasts and now its migrated over to the premium channels like: TCM and others and more by the day.
