As does Virgin, according to an old Metaboli customer, they claimed to get through to Virgins tech department and was told they capped large downloads right off the bat. This person assumed that it was capped only if the download would take them over the FUP but Im not so sure, as casual games in the family section dont take nearly as much, though as most media would be under 10mb it might be they have a limit to maybe 50mb (guesstimate) to allow video files anything over gets capped.
Its also quite possible to make it so that certain places arent counted to FUP or checked, which is why popular download sites wont get capped in this method, though why Metaboli, considering they are affiliated and sold as part of their service, is not exempt from contributing to FUP is really strange.
Though considering with Virgin their left hand doesnt know what the left arm is doing I shouldnt be suprised. 2 weeks ago they finally upgraded the cabling to allow the On Demand service here, I had a query, a simple query about why only half seasons of programs were available, and via their website used their email to contact them. Get a reply about needing to supply account number, my virgin email adress (I dont use them as an ISP), phone number and home address. Provide these and same person responds saying that they only deal with the internet part of things.. you couldnt tell me that in the first response without getting all my details?
Found a web form for the TV stuff and get a reply that sounds more like they have no idea what they offer. Heres a snippet and my thoughts
Thanks for your e-mail to Virgin Media about the availability of full
series of 'Babylon 5' and 'Enterprise' seasons. - I cited these of examples only interested in the Bab5 part.
We're sorry to hear that there are no complete seasons of 'Babylon 5'
and 'Enterprise' available on TV on demand. - you should know if you have complete series, not be sorry to hear
Anyway that got a bit off topic there didnt it, just wanted to provide an example of how useless they are.
