Thanks to some excellent suggestions by member RwAoNrDdOsM I might be able to improve the quality even further a bit.
So over the course of this weekend I will do a workover on the pilot episode and - once finished - will provide anyone who is interested (please PM me) with the episode in 4K or 1080p.
It will probably be available through google drive.
Since I am not exactly sure how long the workover will take, I will keep you guys updated as soon as it is availabe/ready. Check the postings here.
Until then.
