The Youtube video crashed my browser. Boo!
I prefer to watch MP4 videos as-is on Blu-ray players ... assuming it doesn't need to be restored. It didn't crashed Firefox this time. The video looks okay. It has some mild compression artifacts, but otherwise not bad.
For something like this, I'd be somewhat lazy, if I simply had to burn it to DVD. I'd use
ConvertXToDVD, as the source is fine. I'd make a menu-less disc, and it's encode/convert and author in one pass. Stuff from Youtube is rarely worth my time for advanced authoring, editing, restoration, etc. Just save to HDD, watch on TV via Serviio.
