Yes, you hit the mark.
As soon as i set the resume point and playback count to "local only" playback starts working.
If i set it back to "Google Drive Spreadsheet" it stops.

That's what i meant when i wrote about Spreadsheet Issue with Teamdrives. 

Thx, I will look into that issue. 

 Hi, i think i found the reason for the failure and it is some kind of my bad. I put the CLOUD_DB xml spreadsheet in the root of the teamdrive and set the watch and resume option to google drive spreadsheet. I got the folder structure like "[cloud: library]" , therefore i thought it would be the right place for die CLOUD_DB for Teamdrives. But as stated before it results in an error.
A couple of days ago i got the idea, and sorry for my misinterpretation,  to put it into the root of my normal google drive account. Now i can play video files with spreadsheet enabled without and error.
Again sorry for the trouble.
