I should add that I have about 2 dozen PCs here (some running Windows, some needing repairs, several running Linux and a couple of (old) Macs). No way I could prove that none of them are capable, but I could, if TVL came with a warrant to inspect, and a policeman, let them start with an opening comment of "If you can make it work with iPlayer, you're better than me, and I've been in IT for 30 years". Might slow them down, having to check that lot... even getting some to boot may be fun!
(There is no up-to-date Flash player for the iMac or eMac as these are old OSX v10.2.8 or 10.4 machines, not running on Intel chips like the latest. Some of the linux machines might work with iPlayer but I have never tried it on them.
Oh yes, why would I need them to have a warrant and a policeman to accompany them? Because they were told in 1999 after my Mum died that there was no TV set, but have sent pestering letters and threats every 2 to 3 months since that time. No one was living here for around 7 years and it seems to be the case that they unlike the law, where you are innocent until proven guilty, they take the contrary view, and won't hesitate to attempt to intimidate with threats of 1000 pound fine if you don't comply with their request to visit. S*d them, I say. I download around 100 GB of BBC TV a month, (about 17 hours), but don't watch live. I may be 'out of touch' with images from war zones, etc, but from the TV schedules see there is so much rubbish these days I am not inclined to watch (though am tempted to get FreeSat or Sky primarily for the extra radio services which would be in better quality than DAB, or stations I cannot get easily)... I record radio 24x7 and listen a good 12 to 18 hours a day, across the board concerning content, whether jazz or drama, pop or comedy...
