It's not too difficult to hook it up, the easy way is to use a bog standard aerial cable from the RF out of the Beta to the aerial socket of the telly and tune the analogue tuner of the telly to the Beta's signal, you can also check if the Beta has a yellow plug marked 'av-out' that will give a composite signal ( run a normal hifi phono lead to the yellow plug on the telly and select the inputs on the telly remote til the picture appears. The same technique applies to Laserdisc too.
a tip, also make sure the Beta is nice and warm (maybe overnight) as condensation can build up inside and screw up a tape that's put in.
