SKY Recording
1) Reserved 1/2 the disk (it would cache "popular" content from broadcast, a good idea badly done).
2) If you downgraded a package, prior recordings inaccessible.
3) If you cancelled completely, then though you can use EPG and watch FTA, you can't replay prior recordings of FTA or make any.
4) Disc is encrypted.
I've noticed that Android TV on Sony TV seems to want a dedicated USB storage device and encrypts volume and files, even for FTA.
MS has some distance to go to be as evil as Adobe, Google, Sky etc.
