I spoke to someone at Vodafone this afternoon, finally, after initially being patched through to Sky. I had to ring back and press different buttons. Was talked through the factory reset, and pulled out and replaced leads, but it did not make a difference. I am getting a call back in 24 hours to see if the issue has resolved. I have lost rewind and record of all TV2 channels, and the news on THREE. TV1 seems to be ok.
Many thanks for replying Grantt :-) Much appreciated, although I am not sure what a megadata ingest is. Also nice to know someone from Vodafone looks at this forum occasionally. Now if we could also get the Newshub 4.30 news on TV3 to rewind back to the start that would also be great.
