My BT1 HD channel buffers and pauses every Saturday without fail. BT HD 2 is absolutely perfect as are the other BT HD channels. Other HD channels are working fine too. Just BT HD 1 doesn't work. I have to use BT1 SD.
Thanks for posting and I'm sorry to hear you're experiencing some trouble with your BT1 HD channel.
I've run some checks for you and I'm not seeing any issues with signals that could be causing this. Something I wanted to clarify was is this happening on both of your DTV box's? I've refreshed the TiVo® from this end and I would like you to switch it off by the plug for around 5 minutes when you get the chance. We can then see how it performs going forward.
