I have it all good. That 8pm is what my TE4 guide always has for end-of data. When the TE3 boxes get TE4 data, they end at 8pm. When the TE3 boxes are happy the end-of-data and end-of guide are both 2pm on the day following what SI shows as "Program Information To:". If the hamsters are doing their jobs, one TE3 box will get nothing at 2:10am tomorrow, one will get a day's worth at 5pm and the TE4 gets it's normal update. It is curious that the TE4 guide, which get three updates every day, gets its guide's TNA extended even without data.
