Each service differs but if you read the forum policies such a question gets locked because you are asking in assistance to break an agreement (this one is with youtube.)
So this is locked.
I am using the following:
AMD Quad Processor
8 GB Memory
How can I record videos from the internet (like YouTube) . I was using Keep Vid, but now this service is no longer free and they want $29. Any free way to do this. I only record videos rarely.
