i have had my dv-434 since new in 2001. within the past two weeks, i noticed that the player has trouble scanning, with the remote or the button on the player. second issue: when i play certain dvds(only mash seasons 1-5, not any other shows or movies), the show randomly freezes while playing. this is only resolved by scanning, and then it resumes playing. the really wierd thing is that i have watched these shows numerous times, since i bought each of them new as they were released, and i never had this problem until now. any solutions? i have physically cleaned the lens myself, but that really did not change anything. is it worth repair? i have really enjoyed the player, it plays dvds and vcds nicely. any responses greatly appreciated. thanks atrout
