We have a HUMONGOUS issue with Comcast and catching shows when THEIR guide says they're supposed to be on.
Looking at the Comcast guide in my area, we can only view ahead 2 days at the most. We used to live in San Diego and had Cox. Their guide went on and on for days and days and days. It was accurate and great.
The Comcast guide is so full of holes I never know if we're going to get a recording of the correct program or not.
Also, of late, I've noticed that there have been more than a few errors in QVC's program guide. If you add QVC errors to Comcast errors, one wonders what the chances are of recording the correct show.
