I have a problem when playing back recording in EP. It plays back briefly okay, then there is interference on the screen and noise as well, the briefly okay again, etc. It plays back perfectly when it records in SP. I have checked the same tape on another VCR, also a JVC, and it plays back fine, both EP and SP. I also have played back a tape recorded in EP on another VCR. The interference on the screen disappears and the sound is fine, but the picture is very jittery. Hope you have some suggestions to correct this.

Which plug did you change? "EP" stands for Extended Play. A VHS recorder has three speeds. EP is the slowest. A standard 2-hour tape will record for 2 hours at the highest speed (SP), 4 hours at the middle speed (SP) and 6 hours in EP. There is a trade off. The faster the tape moves past the recording/playback heads, the higher the picture quality and visa versa. So EP gives you long recording time at a cost in quality.
I doubt that the unit being in EP mode has anything to do with the cable. You did not say what brand and model recorder you have, but in general, the speed is adjusted with a switch on the front panel (older models) or via your remote control.
The only real cure will be to clean the video head. If that doesn't work then I'm afraid that whatever recorded you EP mode tape was not set up well tracking wise. So other machines struggle to track the tape. Some VCR's will only playback SP or LP tapes and don't have EP mode. In which case you should check to see if these VCR's can play the EP tape and if they can't find one that can.
Most VCR's have a default recording setting for recording speed or other settings. It's just a question of finding the right menu. Have a good look around the menus. However the VCR might default to SP after recording in EP, however the playback should switch to EP when playing.
do the heads need cleaning? sounds like the heads are seriously out of alignment? take off the vcr cover get a philip scrdrv. put tape in. and play. theres an AC head just to the right of the drumhead. jiggle it around gently. u may have to adjust those 3 screws (precison) to put it back in proper adjustmant. also take the tapes u used in that vcr. open the top flap and inspect. are there marks? is there a line going the bottom portion of the tape. if so , it definitely is out of alignment.
Initially, I am inclined to think that nothing is wrong. It is just most likely that that particular tape was recorded in a different speed other than what your VCR is capable of playing. This is a form of compression wherein a longer recording/playing time is squeezed into the same type/kind of tape. The various settings are SP, LP, EP or even an XP.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
the speed in EP is differ from sp ,EP it is much slow then all quality would be less cause you are using less magnetic particles on the tape so here are many reasons for bad recording
first may be you have to clean video heads
or ,you have to clean the path of the tape in the recorder there are some metal guides that turnes with the tape to get it rounds the heads they may be dirty
or clean the capstain pinch roller and its metal roller that makes it run ( the capstain roller )
or you should have new heasd drum sir
