Downloadable videos or webinars

I use youtube quite a lot but unfortunately I cant access it on the train where there is no wifi. Are there any resources that I can use that allow the videos to be downloaded to a tablet?

I have a very long journey home on the train and being able to watch forex videos would be very usefull.

Use a youtube downloader and then transfer the files to a tablet. Mediaclip is an app I’ve used in the past too. Audio books are usually quite good too.

Thanks ill try that
