Description

I am trying to download entire channels' videos up to 12-31-2009. This is happening all over YouTube, where the certain player "html5 player vfl_PLd61" tries to download and can't! And it's always that specific one. It only started happening today. What is going on?! I've tried downloading videos from the following channels today:

https://www.youtube.com/user/cheekoo98
https://www.youtube.com/user/quezon90
https://www.youtube.com/user/nizardbz21

And some amount of the videos from each channel listed all gave me this error and failed to download. I have a feeling that if I attempt to download anymore channels today, they'll all give me this error, so I'm gonna stop downloading until I can have some information about how to fix this problem. So how do I get access to "html5 player vfl_PLd61" exactly?
