Question

Answer 1

an infinite amount of times...just keep the vcr heads clean...

Answer 2

standard length tape will last a long time in security use. consider that they are rarely played, often recorded over again and never played. also you should have a number of tapes, used in rotation, like one for each day of the week, If you did that, then the group of seven should be good for about 6 years.  Using extra length tape will result in drastic reduction of service life and run a greater risk of damage from mis-threading.
