I only watch TV in the evenings so the buffering is probably occurring at the busiest time. I have tried it again but in the early evening and it seems OK at the moment.
The buffering is restricted to BBC iPlayer only. Live TV is generally OK except for a few moments of pixelating that occur every evening regardless of channel. I must say that when we first went over to Virgin TV about 18 months ago we had none of these problems. They are all recent.
Thank you for your reply, life is hectic at times we know!
It's great that the iPlayer isn't playing up as it was when you messaged me. There may be times of which there would be a slight delay loading the content to your TV but nothing as much to interrupt mid way.
I have tested the connection once more and again the TiVo is looking quite healthy, with no signs or error.
