Thanks for the quick feedback and for giving it another try :) Yes, we had issues with ipfs and node architecture in general, but that got fixed by adding fast "hot nodes" and general bug fixings by @meno. If you now pick any video (even the 2 year old ones) they will play. With video age the playback will take a few more seconds but that's an issue with ipfs in general. Excited for your feedback for sure :) (4k support will probably never come tbh)
