Hi aptp66
I've just performed a quick search on my 360 and there's nothing showing for la vuelta, however there are a number of links directed to youtube. You might be better advised looking on youtube as they are carrying extended highlights of the races.
Regarding the possibility of switching to a TV360 box instead of a Stream box. Stream boxes are now the default offering for new customers. There is a small possibility that if you speak to sales on 0800 183 1234 that they may be able to accommodate your request, however if possible there would be an activation fee of £49.99. Any additional boxes after that would be Stream boxes.
Another problem you may encounter is that if you are on a Full Fibre connection (XGS-PON) then VM's recordable TV set top boxes only work on the older DOCSIS network which uses coaxial copper cables. VM's DOCSIS and XGS PON aren't compatable as without coaxial there are no traditional cable television signals just internet, so VM provide their TV service on the full fibre network over the internet using the Stream (Flex) box, hence no recording facilities.
If you are on an XGS-PON connection then you will have a hub 5x - that's the only available VM hub that works on the new network.
