I would like to see them add multiple playback capability. I would like to be able to check multiple items from the DVR playlist and have them play back in a sequence of my choosing. This would be very handy for burning multiple shows to DVD, or for setting up multiple shows to play for the kids.
I would also like to see lockable favorites lists. I know that I can lock out or hide individual channels, but it would be much easier to create a favorites list of nothing but "approved" channels, then lock it in so that no other channels are viewable without a password, and no other favorites lists would be selectable either.
Not sure how it could be implemented in a practical way, but it would be REALLY convenient to be able to set a timer for a show by pressing a button when an ad for it appears. Every now and then I see an ad for an upcoming new show or movie that I would really like to see, but doing a manual search for it is really time consuming. Pushing a button when the ad comes on to set the timer would be very convenient, and could also show advance interest in a given program. That's something that programmers and advertisers alike might be interested in. It could create a kind of ad rate futures market.
