...my wife says TOO MUCH! (^^,)
But I like to do it, and it's a creative process... instead to be a couch potato, sitting in front of a big TV watching stupid television programs, I prefer to be a couch potato, sitting in front of a big TV - used as monitor - creating something interesting...
Usually, I spend about two/three hours a day; the least time is used for capture/rip; the most time to process, test, upload, receive feedbacks, reprocess, retest, reupload etc.
...and you?
