I have tried dvdvideosoft's Youtube to DVD converter, but each time I paste the youtube URL and click the Create DVD Button, it throws up an error reading file.
I tried with the DVD video soft software and I have not any issues occurs during the translates videos from YouTube into DVD convertor. I would like to suggest you that enter valid source URL to convert from YouTube into DVD convertor. If it does not work yet then you will need to reinstall them.
