Any Freeview HD branded device that records to external media will add mandated DTCP (I believe - not sure if other encryption is allowed) encryption to HD recordings, to make sure they can only be played on the device that recorded them. (In fact I believe it has to do the same for internal storage too - so you can't remove the hard drive and play them/copy them)
The Freeview HD broadcasts themselves aren't encrypted (the Freeview HD EPG
data is compressed using proprietary Huffman tables though) - but Freeview HD licensed devices must add encryption to recordings.
These two measures were introduced to allow Freeview HD NOT to be encrypted for broadcast (they were deemed - good enough for rights holders)
If you have a non-Freeview HD licensed recorder, or use a PC with a DVB-T2 tuner, this is a non-issue - the recordings are clean, unencrypted, and play in VLC, MPC-HC and most other players. (,TS is the most common recording format - as it is basically the MPEG2 transport stream that is being recorded with PIDs carrying AAC audio, H264 video etc. NB MPEG2 TS doesn't mean the video is MPEG2...)
(I believe the same rules also apply to Freesat HD devices)
