i've had this recorder for a while now with no problems at all untill recently.
1) when i record something on the recorder and try to play in a different dvd players the video freezes and skips a lot to the point of its impossible to watch.
2) when i try to watch dvd's that i've burned using imgburn the video freezes and when you try press forward it skips around 20 mins into the film.
3) some disks (not burned by me) freeze seconds into it playback leaving the only option to pull the plug out because the eject button wouldn't even work .

I never had these problems before and i use the same dvd-r's. I cant pinpoint when this happened or what i did before the faults because i rarely use it.

Any ideas what could be wrong with it?
