I think Watchdog is often full of crap.
Firstly: That technician is utterly retarded. Does he honestly think Virgin Media actually run the data centres which host streaming media? No. Buffering is due to lack of upstream bandwidth or server resources at the host server which is completely out of Virgin Media or any residential ISP's control.
You're right in the sense that Virgin isn't in control of everything you'll do with your Internet, but you're mistaken if you don't feel they play a part in most streaming media.
The likes of google are pretty damn good at streaming media and when the likes of BT FTTC users don't generally have any problems streaming from these services. Virgin users often do, for numerous reasons.
#1 - Utilisation issues
#2 - Less than steller peering agreements
#3 - Bugs in the hardware/software they almost force you to use (we have modem mode now).
If you streaming experience is inferior to the competition* despite headline speeds then you have a resonable gripe consider they've locked you into a 12 month contract. In fact if they've got you to use them instead of another company because they've promised you something they're not in resonable control of, you have reason to gripe. The reasons they won't deliver what they promised doesn't really matter.
In addition to this Virgin hasn't particularly ran the fastest or most reliable DNS servers for most folks, something which can dramatically change the experience of your connection if you don't know how to change it. They also got a slap for claiming the best gaming performance which is definitely a load of crap. Pings have nothing to do with headline speeds, and VM pings are fairly inconsistant when compared to BTs (though either could be better depending on your line / area). They talk a load of crap, but in reality they're not really a great ISP (imo).
* To be fair in my opinion much of the competition is crap.

Secondly: They are doubling everyone's speeds. The reason that dude is getting 0.5Mb/s is because he's on a high utilisation UBR. It doesn't take a telephone call to install miles of new fibre to handle bandwidth overheads. It takes weeks of laying new cable and can require planning permission from councils. I had the exact same issue of high utilisation about 12 months ago. But they did fix it in about 7 weeks, and now my internet is absolutely spot on 50Mb/s. In fact the software limit set in my modem's firmware is 53000000 bps and I get EXACTLY that amount in speed tests. The fact that there is no "syncing" involved in IP over CATV, as opposed to A/DSL means that I get 100% of the advertised bandwidth.
They're not really doubling your speeds if you have utilisation issues though. Normally I'd agree that 'issues' don't count if it weren't from the fact a) you're locked into your contract and b) they don't fix it for most people in any resonable time frame.
The whole doubling of the speeds is a load of crap anyway. I had quite a nice unfiltered 50Mb connection, they state they're doubling my speeds (still not happened, this was a year away) and have used it to throttle me to 25Mb a second. They've effectively halved my connection. Even if I were on 120Mb in reality actually using the connection would leave me sitting on 60Mb, less than what I could effectivly use on a decent FTTC connection all day long.
You do make one solid point though, the up-to speeds is the biggest ripoff in Britain. The regulator should have us paying up-to amounts, I'm fairly sure the big players would be quickly less timid about upgrading their networks if it was going to hit their wallets.
