Back in the analog Days I bought some REPLAY TV's.. alas they no longer make them (Did nto make the transistion to Digital) They were rated as the #1 User interface..> DISH network based their user interface on the Replay (But the Replay was still better) Last owner of the Replay was DirecTV.
I was not aware it did not allow OTA shows to record.
There are many.. Direct's original User interface was based on TiVo. I do not know if Direct has updated but if you like their User interface. Try a TiVo. See if you can get an in-store demo however
Based on the fact TiVo sued Direct and won.. I suspect you will like it.
Now I'm using a Spectrum DVR.... Which SUCKS EGGS far as User Interface is concerned.
