Hi, I have a SD-4700 dvd player, and after 10 months of operation, last night when I was trying to play DTS dvd, there is no sound coming out of it. The dolby audio works fine, but it just won't work with any of my other DTS dvd. I put another DVD player (SD-4800) in, and it played all of my DVD's fined, so it seems that it's the DTS portion of the 4700 that went bad. Is this common? What would be the fix?? Or is it worth it to get it fixed?? I got a quote from toshiba service center, and it will be ~$70-120 on labor to repair. The 4800 is going for ~$200, it seems lame to pay almost 1/2 the cost for repair on a new one. any suggestions or opinions will be appreciated.
