Vcr tried to eat several tapes it would either eject properly or leave tape routed through all rollers but, after taking cover off and watching cylindrical head was turning and engaging etc... ;. Tape spindles would rotate about 10 degrees and then would get eject message on screen; but tape would not come out unless power turned off. After carefully watching tapes in and out and messing with tape entry mechanisms; noticed that the rubber coated roller mechanism which engages on the side where the conical pin fits in the tape had more resistance than what i thought was normal. Why did this happen; after several, well many cycles of unpluuging and plugging up and many different tapes the problem resolved itself for now. whewww! at least it did not eat tapes up completely like old machines, just wrinkled section around rollers.
What is the most likely cause of this problem and how can i be sure to avoid creating the same situation again.

Re: magnavox msd804 vcr/dvd combo
I think what you are referring to is the pinch roller. This roller sits at the right side of the mechanism, and in play mode, presses the tape up against the capstan shaft. These pull the tape through the machine at a precise regulated speed. If the roller isn't being engaged or the capstan isn't turning, then these conditions need to be corrected. Does the capstan turn freely? How about the noted roller? Perhaps lubricant has dried/hardened/gotten sticky...
There is electronic circuitry for the capstan motor (a direct drive type motor integrated on the underneath side. Something could be awry with this circuitry.
There is a drive clutch mechanism which could also be defective. This drive clutch assembly sits in between & swivels between the supply and takeup spindle, depending on whether VCR is in Play/FFWD or REW. In the Play/FFWD, it is engaging the right spindle (takeup) and in REW the left spindle (supply). If this is what you are describing, perhaps this clutch unit needs replacement or the grease at its pivot is hardened/sticky.
Most VCRs of the last 10+ years don't use a rubber tired drive (very common on late '80s VCRs), rather a gear toothed drive.
Beyond a simple mechanical problem, repair might not be economical feasible. Most VCRs of the last 10+ years are poor quality, disposable, unlike the machines of the '80s and early '90s, which were built like tanks comparitively speaking.

VCR's will eat tapes in several different places. The only way to see where is to take off the top cover and watch it doing it. You will need an old tape for this.
The must obvious area is the roller area, with the roller itself to blame especially if the tape has crinkles on the edges. Also look around the mechanism for signs of damage to the plastic parts.
Lots of parts can damage the tape. For example if the tape is not pulled back inside when it ejects. Another good cause is the pinch roller being damaged or out of place.
The best way to find out is put an old tape in the machine (or at least one that you don't mind be chewed up, whilst the top cover is off and you can watch the tape playing. You should be able to see the problem then and take action to correct it.
It sounds like the tape is jammed in the vcr, remove the top cover of the machine this will expose the tape. If the tape is spewed in the mechanical section and around the video head, get a pair of scissors and start cutting the tape and carefully remove all tape particles, when all tape debris has been removed, plug in vcr turn on and eject. If the tape looks good, you may have a loading basket problem, bad idler ***. or broken drive belt. "Lets hope for the best"
This is caused by mechanical problems in the VCR. Depending on the age and maker of the VCR, the take-up reel in the cassette is driven by a gear, a belt or a rubber wheel. This isn't happening properly in your VCR, so the tape is piling up inside. Given the low cost of replacement combo players (I don't think you can find just a VCR these days), it's not worth having repaired. You can expect to spend $60 to $100 on a repair for this kind of trouble, assuming there are even shops still willing to take the machine in.
You can try cleaning it with a VCR tape cleaner to see if the pinch roller have build up on there. It could be that the motor isnt feeding the tape up against the recording heads properly and may need an adjustment. If you can take the top cover off, you should be to see what the problem is by the way the tape is being inserted into the machine.
What do you mean 'Tape crunches" Do you mean that there is tape slack, which then crunches when Tape is lifted during Eject? If that is the case, then the Supply Reel Roller Brake is bad. it is a Felt Pad, which needs replacing.
If the entire eject operation is wonky, or if it's timing is bad, then I suspect that One of the eject Gears (On either side of the Mechanism) is damaged and needs to be replaced.
One question, i assume that you are able to eject the Tape eventually, and so - Does the Tape Load into the VCR properly, when you insert it into the machine? This will help me in giving you a better diagnosis.
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.
