Thanks @Earnie_C & @Graham_A. Although I was a VM customer a few years ago, after Sky put their prices up (when I was very near to the end of the contract) I took the opportunity to jump ship and return to VM. I've only had the gear (and installed TV Go on my compatible Samsung tablet) since yesterday so everything is new!
Although it looks the same as the old V6 box, this new TV360 box is a very different beast. I take it that you guys are still on V6 boxes because the only way to download programs to my tablet in TV Go was from the set list provided on VMs site through the app and NOT those stored on my TV360 box.
If either of you (or anyone else) can tell me specifically just how to get my box recordings to download (not just stream) onto my tablet, please tell me your secret because I don't see such an option. With Sky, there was a slightly different/better version of their app required to download programs to local tablet storage - the version of TV Go from Google Play Store that I have seems to be the only one though.
