how do i fix my recorder and video DF 4501P?

hi all

i have a daewoo DF 4501P vombi video/dvd recorder

The following faults are:

The video tapes are being chewed up (new ones) and when a head cleaner was put in it kept on popping back out. As this was the only time I used the video player to copy a social event to dvd this did not work out.

The Dvd player is not recording properly, not erasing a disk properly, when on recording it keeps on pausing itself. I have tried about 100 RW disks from 10 different makes, and bought 5 different dvd cleaners and none of them are working saying that unknown disk.


any ideas would help please
thanks in advance
