Going from directv to cox then to YTTV our only gripe is the DVR. It records every show ever, not just new shows. And it doesn’t mark them as watched nor can you delete any (AFAIK).
If you infrequently watch a particular series, it’s hard to know what you watched already when you go back. You either guess or watch for awhile until you figure out you already saw it.
We do like being able to arrange the guide in the order of channels we prefer. And multiview is awesome. Had NFL, World Series and an NBA game on at same time
