Are these individual files and not a copy of an album? It sounds like your DVD is a compilation of .wav files with a buffer of x secs duration inserted by the burning software between each track. So there is a 24/192 .wav track which Rossini recognises and plays. Then there is a gap of no discernible format so Rossini does not know what it is supposed to be playing so reverts to default ( that may be 16 or 24 48KS/s and/or it mutes ) then it is sent another 24/192 .wav track so it switches from default/mute back to 24/192 ( that is the relay you hear) and so on.
The only way to stop this is to make a DVD disc that maintains the same format throughout. This may also enable your player to stop muting itself between tracks if that is also occurring. This would seem to depend upon your burning software and player. I don’t think that there is a solution at the Rossini end of things including using the buffer option as it is not in operation with 192 material for sufficient duration ( only a fraction of a second).
The relays used no doubt have a rated life of many thousands of operations but how this manifests itself in listening time must depend on how many of these DVDs you make and how often you play them.
What is your purpose of making DVD rips in the first place? I would say it is unusual as most of us will rip to computer storage.
