I can see you are in need of information to get your VCR working properly. I was able to find a link that includes a community conversation on the Yahoo website. I would suggest providing the make and model number of your VCR to better assist the expert. Just add to this thread. I hope this is helpful.
Unfortunately, when the tape will not eject can be a mechanical issue or an electrical issue. If the tape tries to eject, but wont then it is normally a mechanical issue. Either one can be difficult to troubleshot and fix. I would recommend replacing the unit.
