It's only an issue if you insist on real-time streaming. 2:1 is pretty
good when you're talking lossless. And the local broadband (NTL) is
changing their standard to 10MB/s this year and automatically
upgrading everyone with 3MB lines.

* 10Mb to become the standard cable broadband speed for ntl customers
* All ntl Broadband customers eligible for 10Mb upgrade at no extra monthly cost
* Current 3Mb customers will be the first to receive the new service

and really, that 10:1 isn't REALLY compression, it's decimation.

I'd be happier to wait and download.
