not sure if it's the right place to ask, but it's quite hard to find some forums to ask about VCRs.
So, I have a "SEG VCR8000" which is just a rebranded Shintom VCR, it's 100% compatible but with less quality I assume.
So, my issue is that upon pressing the play button, the tape is pulled out, attacked to the tape head, and only the LEFT wheel on the cassete spins, but the RIGHT one is staying still which causes the tape to be rolled up outside of the cassete causing the VCR to stop the playback automatically.
Interestingly enough, the Forward and Rewind functions work perfectly fine, but Play the being only one who doesn't work.
I opened it up, to take look at the belts and one was too large due to age, and one was totally broken. I replaced them both, and the system is up and running again, but playback is still giving me issues. I don't understand how the whole system works, or which belt is for what, but everything spins when it has to - none of them is slipping or anything, all of them have traction even at low and high speeds.
As a side note: the VCR is equipped with a screen to show channel, record, vhs info etc. which doesn't work, also I saw no input on the SCART on my TV. So I'm afraid the electronics are fried or something, but I assume that there has to be a tape playing to the signal to show up (?). But this seems like a mechanical issue. Still, expert help is needed. Also, I tried multiple cassetes, so they're not the issue.
Here is video of the issue and a image of the backside where the belts are.
Thanks in advance.

Repairing a VCR is not the average person's task, It require tools, knowledge and patience, It is not something that can be done over an online forum, If you don't feel comfortable taking it a part and check all the mechanical components for defects according to the service manual it is time to get a working VCR and move on. A lot of people get pissed when I say this but it is the true reality unfortunately.
I have an EE degree, and fix all sorts of things, but I agree that VCRs are particularly tricky, unless you have lots of specialized equipment. I have fixed some, but have failed more often than I have succeeded.
However, if you want to continue to work on it, you need to look at the other rubber pieces. If the belts had lost their elasticity and one had broken, that indicates some pretty brittle rubber. That means that the pinch rollers are also probably shot. Those are what actually manage the tension around the heads, etc.
You can get some rubber rejuvinator and carefully apply it to each roller, and then after thirty seconds, wipe it dry. This won't fix anything permanently, but if it starts to function a little better, this can help you determine whether you need to replace these items.
But I am lacking the experience to be able to fix something like that. I just can't understand why forward and rewing work perfectly but play won't. But that's my lack of understanding how the machine works.
Thanks for the reply.
Could also be that the takeup mechanism is worn because the right reel isn't moving to take in the tape that pinch roller is supplying.I think,therefore i am a hamster.
The play and the FF and REW funtions use different sections of the tape transport mechanism. When you press play the right spindle uses a clutch system to take the tape back. In FF usually there is a direct mechanical connection to the spindle and that's why there is a different behavior. To fix the problem you should take apart the spindle and check for the material between the spindle and the weel under the spindle.
