It's not that easy to say cause it varies. But in general you can say that for a ordinary movie (let's say 90-120 min) there between at least 3 but not more than 7 dropouts!
As I said there are no dropouts when using hdmi! Just to make it clear again 😉
I've broken this out to its own thread so we can get into specifics here. The software team is investigating this and would like to know the make and model of your DVD player and TV. Also could you let us know which version of software or firmware both your DVD and TV player are running? Please let me know.
