YouTube Video downloads

I am an avid collector of European LGBTQ cinema. Many of the movies I like are independent films not of the scale to be released to DVD so I must watch them on YouTube. Many of these movies are not uploaded to YouTube with optional English subtitles. I just want to capture them and burn them to DVD for private viewing purposes and not for any financial gain. I have a very unique program on my computer that will allow the uploading of the video to their website and then be able to remove any subtitles completely and replace them with subtitles in a vast variety of languages. This is a membership only website and requires a monthly subscription fee. I have the professional edition which allows use of the subtitling option. My issue is that I don't have the technical skills to utilize the website so am looking for someone with the technical skills to operate it for me.I previous employed someone who successfully performed this service for me however I know longer have access to them. If you want to know more about the features of this device go to www.veed.io for further information and then we can talk further.
