Yes, it'll be fixed by the next software update

Re: Mpeg4
 
Am I reading the bitrates incorrectly or does the move to MPEG4 look a little underwhelming?

From digitalbitrates, Virgin MPEG2 is showing an average of 16.6Mbps for BBC One HD, Virgin MPEG4 is 11.9Mbps and Freeview MPEG4 is 4.7Mbps.

Would we expect Virgin's MPEG4 to be at a lower bitrate?

Unscientifically recordings HD recordings on a V6 seem to eat up less % of disk space now but it's not a very granular measurement.

Yes you should expect much lower rates as it's a far more efficient codec so can produce the same results as mpeg2 with a smaller file size/bit rate.

Do you know when this is due?

Probably. It's currently on pilot, and will be rolled out nationally if the pilot is successful.

Until Virgin come up with other uses for the space it is likely they will use high bitrate MPEG4. When they squeeze in more channels, or reallocate it for broadband, we will see lower bitrates.

Thanks, that makes sense. Virgin can't win really, high bit rate and I'll moan about the space taken up for recordings, once they lower it I'll moan about any degradation in picture quality. I'll bask in the high bit rates for now. ;)

Could the V6 do h.265 if it ever materialises onto VM?

Looks like there are a few issues cropping up on the Community forum.

Some VHD & V+HD customers reporting their HD channels at reverting to 4:3 aspect & they cant change it.
I'm getting that on BBC News HD. Not noticed it on other channels, not that I watch many others.

Interesting links, thanks.

Begs the question, why the need for ever faster broadband connections, when the compression technology is leaping ahead so far?

If a UHD film can be streamed at 6mb, what is the point of my current 200mb connection, let alone 300mb or a future 1gb service?

No idea, it could be automatically part of the chipset being used, or not.

The faster connections allow for multiple devices to be used at the same time.

We've gone from a time where you'd use one device with your connection, to basically everything being connected.

I hope they don't fix it, means you can FF through the ads twice as quick. Best bug ever ! ;)

You could before by pressing FF again.

You can't go faster than 3 fast forward arrows, and the bug makes that speed twice as quick. It's brilliant, keep it.

Netflix and Amazon say you need at least 15Mpbs for their highly compressed UHD streams. BT will not offer their UHD service on a line which can not constantly achive 44Mbps.

If on your network you are not going to have several users taken up a lot of bandwidth then you don't need more than 200mb.
