You gotta' say one thing about OpenATV. Awesome out of box experience. I think stepping back a few is in order.
Performance issues like scanning. Initial setup similar for all E2 images. But one thing is for sure.
If you have a receiver with ATV running and slap the remote control next to your TV remote. There is little to no learning how to navigate through the array of buttons to get the most simple and straight forward things to happen.
Not everyone jumping into the FTA thing will have had 17 receivers or tried the mess of E2 image incantations. I think "somebody" is missing that.
The Germans are smart. And ergonomic.
OpenATV gives you that. Performance issues aside. And bells and whistles. I believe that they still shun the main one thing that makes satellite TV fulfilling.
Although it might appear that someone has perhaps made their own version of the ATV image. Maybe. I don't think it's that big of a deal.

Here in the CONUS. For us at least. Blind scanning is important. Not so much for a noob maybe. I stick every single blindscan result that has new transponders in my satellites.xml file.
And almost immediately when trying a new image. A backup of it gets stuck in tuxbox. And any other file system location that may contain it.
Why in the heck spend all of that time doing a repeat blindscan when you do try or happen to use ViX, TNAP.....? Well?

And since the subject was ATV. Being out of box friendly. A dude in another site was touting PureE2. ViX is my every day image now. I like it. The other 3 slots are loaded with.....
OpenATV 7-something, TNAP-whenever-I-used-it-last, and nothing. Blank.

If an E2 image has me hunting for buttons. Hitting Help for a keymap layout (ViX kinda' dropped the ball). If I may be so blunt. It gets shitcanned.
You know what is missing from PureE2? A rusty coathanger. You make what you want of that one.
Complicated Kodi-ish clone. And the touter of it ranting that you have to "learn it and forget what you've used".
BS. If I turn on der hot vasser. I vant hot vasser. Not a Heineken that's been in the sun for a week. Channel UP should give you the next channel up. Not a headache.
Punching Video better not give me Ren and Stimpy reruns.
The bin.

Christ. A Sony in the living room. A Visio in the bedroom. An old DLP with a color wheel-a-spinnin' in the garage. Turn it on. Choose a channel (easily and the same on each single one). And hopefully you catch the very, VERY tail end of the Taylor Swift halftime show on the game. On purpose!
Lol!!
Kirk out.
