Page 1 of DVD to VHS on Dansai 852

I have to transfer Harry Potter to VHS but i am having a few problems.

Firstly the sound is very poor, sometimes it is very quiet, then it returns to normal level.

Also although the film is playing correctly on the TV it always misses the end of the film, even though the video is still recording.

This is a R2 copy of the film, and the macrovision has been removed in the menu. The sound output is set to analogue and the volume is on maximum. I have also tried another video just in case the one i was using was duff.

Can anybody help?
