VCR to DVD problem

[cotcot]

I copied a video film directly from VHS to a DVD player/recorder (Liteon). The video is a collection of clips from an old camcorder on a VHS casette (not commercial). The copy on DVD plays fine in the DVD player. When I put the DVD in the PC the DVD is detected as blank DVD although I am sure that there is 2 hours film on it. Looking to properties is also giving blank.

Other DVDs (also commercial) playback fine (I have libdvdcss etc running OK).

Any ideas what to do to get the copied DVD running on the PC ?

Thanks

I saw that the disk is not closed.
Seems to be an issue with the dvd-player not having enough free space to close the disk.
