Most of the channels are off by about a half minute. Now, this is not a problem on the front end, but the recordings stop before the show is over, and that IS a problem. This is not one channel, but many, including all 4 major networks.
Yes, I know I can extend the recording, but that presents other problems - interference with the next show that is recording. Example: if I extend an 8-8:30 show on CBS to 8:31, but 8:30 has recordings set for FOX and SyFy then I get the popup that there are three recordings and I have to cancel one - a big problem if I'm not home to make the selection on my own.
Yes we notice and we hate it. The end of a show is often cut off--it sucks that you have to add time or guess just to see the whole show. I don't know if it is the guide or the individual channels. The guide is wrong a lot, so I don't really trust it.
