I have a JVC XVD723GD DVD Player that has spent 8 months out of the 18 that I have owned it with the service shop. Let me start at the top: I bought it with an extended warranty. I first noticed a problem when it wouldn't work with the Guns of Navarone DVD. It wouldn't say "no disc" or anything like that. It would just eject the tray a few moments after I closed it. At some stage I got a letter from TWEETER saying that if the player had been freezing up, I should take it in and it would be replaced for free. While mine was not freezing up, I figured that it DID have a problem, and surely the freezing problem would also surface and that they'd surely fixed it in the current production units. So I did take mine in and got it replaced. The replacement unit started freezing up and nothing but pulling the power cable would reset it. I took it in for the first time, and the service slip said that they had replaced the laser and fixed a short in the power supply. Then I bought an DVD of an Indian movie, Lagan and another one called Angoor. With Latter, it would do exactly the same thing that it did with Guns of Navarone, but with the former, it would play fine till it got to chapter 28, and then the picture would start artifacting badly, the sound would go out of sync with the video. The video would get worse and worse, until the thing would stop dead and eject the DVD. I took it in again, and when it came back, they had replaced the laser again. This time Lagan would play 99% fine with only some artifacting and audio/video sync hiccups. Angoor, which would not play earlier, would now play but would do what other one used to do. I.e., it would play fine, but then well into the movie, it would start artifacting, audio and video would go out of sync, the picture would go all the heck and then the disc would be ejected. These two discs would play perfectly well on every other DVD player that I tried them on. EVERY SINGLE ONE. However, there is a possibility that these DVDs don't meet the DVD specification. However, the player would intermittently exhibit video artifacting and would stumble once in a while (frozen or dropped frames, audio out of sync with video) with DVDs like Spy Game and The Man Who Wasn't There, and lots of others. I took the player in again, and this time it came back with the note"no problem found". I went in to speak with the manager who said that they had been unable to verify any problems with it and that my Indian DVDs were bootlegged and therefore the player didn't play them and that was normal. I asked why it did it with Spy Game. No satisfactory answer to that. I said that with confirmed good DVDs, its an intermittent bug, that it doesn't cause the player to stop running, so unless you are watching the screen at all times, you'll miss it. He tells me that the service tech has 20 screens with machines running on all of them and he watches all the screens simultaneously, and would surely catch anything that might go on. I found that quite ridiculous that the service tech sits and watches all 20 screens all the time tests are on, and can see intermittent problems in all of them. I reject that this could find my problem. I was quite upset because I felt that their diagnosis procedure was by design going to skip over intermittent, short burst problems, particularly if you weren't actually listening and paying attention to the sound track. After some heat, the manager said that they would take it in one more time, and if it didnd't work we'd go from there. I specifically said that if they watched Spy Game and listened to it, they would see what I was talking about. I had no hope because I knew they would only repeat the tests they did earlier, and they would not try the Spy Game DVD. Sure enough, 6 weeks later it came back, "No problem found". I asked the manager what he intended to do. "I don't know that I can do anything. We can't do anything about something that we haven't found". After some discussion, he said that the player would be sent to JVC for their diagnosis. And if they couldn't fix the problem, it would be replaced. If they didn't find the problem either, well then...... I am concerned because I am fairly certain that JVC's diagnosis procedures are probably no more thorough or investigative than Tweeter's. I am certain that there will be no resolution here to my satisfaction. SO what should I do?
