We got Sky Plus at the beginning of December.
I dont know or can never fathom the technical issues so I'll leave that to others, but what I can tell you is that we took up the offer and got the package for £160 - plus £10 per month extra. We had to agree to keep this package for 12 month.
They then came along and installed a new box in the lounge with a new handset - this is the PLUS box. This came with a new Card. The original box was then installed into another room in the house.
The reason we decided to go with this option was basically because Chris likes to watch Skysports and the music channels - my mum likes to watch the soaps and she likes the UK Channels and also Hallmark. By having the second set this gave us the flexibilty. I record the soaps and I watch them early the next morning when I get up and do my ironing - so we all get the flexibility we want, when we want.
But.........the best thing is that we never miss a programme. We like Friends and ER - you can just press a button to record and then press another button, and the Sky Plus automatically records every episode......you dont have to remind it. So you never need miss it. Also, if you are watching a programme, even a LIVE programme, and the phone goes, or someone knocks on the door, or even if you want to make a cup of tea, you can just press PAUSE - and it freezes the programme/film - and automatically starts recording the rest. When you're ready to start watching again you just hit PLAY and it carrries on from where you PAUSED it - in the meantime carrying on recording, so you are basically playing catch up!
I think it is a brilliant system and it works really well for us - I dont have to sit and watch what I want where everyone is smoking all around me - I just disappear off and do my own thing and watch my programmes when I want.
Sorry if this is all a bit jumbled but I couldnt think of how else to put it! LOL
Hope this helps - we think it is worth the money, since we moved we are not near a video shop so we can now record as many films as we like and watch them at our own leisure.
