Only plays back in fast forward and rewind

SOURCE: My VCR is egecting the tape with the casstte adapter.

The cassette adapter uses 1 AA battery. When you place your VHSC tape into the adapter and close the cover, you will hear the motor running and the red piece on the adapter will move inside. Check the placement of the battery and make sure the clear shrink wrap has been removed from the battery

It may need to be cleaned. Mechanical problems are one of the big problems with VCRs they use alot of mechanical moving parts and play for so long they fail. Plastic parts dont help much either. The pinch roller takes up the slack and is usualy the part that fails first because it constantly runs along the tape and builds a coating on the rubber so it doesnt grip the tape and pull it back into the cassette. If its not pulling the tape back in then it hangs up inside and you cant get the tape out. Fastforward uses the reels to pull the tape not so much the roller. Try and stop 2 times then fast forward then eject the tape. Try and eject the tape while its fastforwarding so it doesnt do anything else. Sometimes machines will unload after its been in fastforwad a while then it will eject. You will hear a change in the sound when it unloads, you can hear the mechanical arms move the tape in and out of the cassette. Thats when you eject it. You cant really clean it till you get the tape out. YOu can clean the pinch roller with fingernail polish or paint remover. It is a wheel inside it looks like a black tire. It pinches the tape against the capstan arm this is why it developes a film or a shine on the rubber making it slip.

I have the same model and I also had that problem. It turned out to be the motor. Do you hear a faint humming sound? If this is similar, you will have to take it to a designated JVC repair shop.
