Multiple laptops and PCs (plus multiple OS and browsers) over the life of ISky and now Sky Go but have never managed to get more than 5-10 mins of use before I get some error or another - usually a concurrent stream limit reached or variation thereof.
The glitchiness of it is such that I have virtually given up on using Sky Go - the frustration is such that I would rather record it on MySky and watch it 24 hours later than have the viewing experience totally ruined.
A scan of forums (geekzone and others) would suggest that this is not uncommon for either Sky NZ Sky Go or the British system it appears to be based on.....
Any suggestions gratefully accepted but not holding my breath!
