It does seem like there’s a problem with the player, because nobody here seems to have a similar issue. I am not familiar with your model. I’ve had my player (Oppo 105) for 7 or 8 years and haven’t been looking for another one. I can imagine a deck that has a setting where it can add a gap between songs, but I wouldn’t engineer such a “feature” into any product I designed. It might be that your player has such a setting that could be changed, but I don’t believe that’s very likely.I'm afraid I bought the wrong player.
I managed to found on a well known German forum some testimonies from people who complained about the exact same default with Yamaha DVD players of the same family as mine (use an online translator if you do not read German) :

According to one person who sent back the player to Yamaha at the time, the response was : "No firmware update will be released".
