Dell-tech,
The Nova DVD player that I have is the DVD689i, same model as that of Monzki's but without the Bit rate determining capability. It's almost had the same capabilities as that of the Xtreme DVD player, but I had a problem with it's remote control, which seemingly malfunctions once your beyond five feet from the said player,hence, I had it changed after a day in my possession. I noticed that the Nova DVD players, are a bunch different form another since, we had a hard time looking for the particular remote for my model, even though,the Nova players remotes' alike.
The Nova has been with me for the past two months, and so far, I noticed that it's rather more selective than the Xtreme in playing DVDs, I have not experienced the skipping that you have described, and hopefully the model that I have is far different from the model that you got.
Now regarding your problem, there is still a solution for that, you can take it to a repair shop in Quiapo, the technicians in Quiapo are now quite versed with "Lens' problem" and you can wait for your player since, they can easily resolve it in a few minutes.
