Hi, I am having really bad VHS playback issues. I was transferring some old home videos. for one tape this damage where the image duplicated and moved up and down was present for the first half-hour then came back periodically throughout the tape. it was not laying flat inside the VHS tape, (there are example images I attached. they are not the same tapes but you will get the idea of what I am talking about when I say bumpy or flat.) then I thought to rewind and fast-forward through the tape 2 times. I thought that might fix it because the tape was laying bumpy like that. it worked. the odd damage was gone. but then there was another VHS tape I was ready to transfer but there was the same problem and rewinding and fast-forwarding the tape a couple of times did not help I still thought it might have something to do with it looking bumpy. I linked a video of the thing I am talking about.

I do not know what to do to fix this. just so you know I know that this was not there the last time the tapes played.
