Mike Dimmick: looking at the "Blue Book 7", it rather implies the change is just to increase the capacity of the multiplex from 24.13 Mbit/s to 27.14 Mbit/s

Option 1 - 2k (1705) 64QAM 2/3 1/32 24.1283422 Mbit/s
Option 2 - 2k (1705) 16QAM 3/4 1/32 18.0962567 Mbit/s
Option 3 - 8k (6817) 64QAM 2/3 1/32 24.1283422 Mbit/s
Option 7 - 8k (6817) QSPK 1/2 1/32 6.0320856 Mbit/s
Option 8 - 8k (6817) 64QAM 3/4 1/32 27.1443850 Mbit/s
"For the Option 8 mode, transmission trials have started. It is too early to say whether the above modes under consideration will be specified for future use. It is felt prudent that performance parameters for Option 8 should be specified in this version of the D-Book. However at his time, receivers need only be tested ... with a small sub-set of the Option 8 performance parameters. "

p3tr3v: The reference book for Freeview says
"The receiver shall be able to output any multi-channel audio, regardless
of the broadcast encoding, in one of the following formats, presenting
the same number of channels as broadcast:
AC-3.
DTS."
It also says of AC-3 "Audio codec. Also known as Dolby Digital."

Mike Dimmick: I'm sorry about the confusion, there was a period of time when there was only 2.0 digital audio on Freeview HD, whilst Freesat HD carried 5.1.
I wasn't sure if this problem had been resolved as there is no Freeview HD signal here for me to test.

David Harold Constantine: Turn sharpness off.
But yes, the pictures will be blurred in SD, that's why HD was introduced.
I presume you are using an HDMI cable from the box to the TV?

Andrew Mark: As I said, if you are so bothered about watching a different BBC region, use Freesat.
