Ask Slashdot: IPTV Service In the UK?

New submitter OlivierB writes "I am moving to a new house in the UK. The house will have very fast broadband but there is only one TV/cable aerial to plug into which is also very inconveniently located in the property. The cable TV provider can move it (for a high fee), but the biggest issue is that their channel packages are just too expensive and not appealing to me. Ideally, I would like access to the UK Freeview channels, and maybe a few extras such as Discovery Channel, Eurosport etc. All of this content would be available via IPTV, which I could watch from an HTPC or simple set-top boxes. Do you have any ideas to share with me?"
