routing for idler belt in JVC BR-S378U

[Darren]

The belt appears to have popped off the idler on this VCR unit. The belt itself is intact, so something likely became stuck due to inuse.

I can't figure out the routing to get the belt back on. The belt seems more than double the size required to get it from the motor to the idler. There's no way the belt stretched to 100% its size from not being used, so I'm assuming I'm missing something.

Would anybody be able to help me with the routing for this belt? At least to get it back on, so I can see what is sticking if it pops back off again when trying to rewind.

Any info would be appreciated...
