After being directed to this specific thread by my Comcast chat representative after asking where I could make a suggestion to Comcast about DVR features, I read through this entire thread and I am not sure I agree this is the best place to make a suggestion.
However, I would like to add my vote for being able to record by keyword on the X1 DVR as I used to do on my Comcast DVR until I upgraded. My rep seemed to imply that this one is better because it records shows more "specifically" but I had several keyword searches on my old DVR and I was specific enough in my word choice that it only recorded things I was actually interested in seeing.
I'm generally pleased with the new functions on my X1 set-up but I am really disappointed in this reduced functionality of my DVR.
Thank you,
Dawn
