Hi Piotr

I think you already mentioned this before. I am not sure how this would 
work.

When I watch recordings I always select the program on the left and then 
see the episodes on the right. In that case, all the episodes for the 
program are already displayed.

Your change only makes sense if I have selected "All recordings" or 
"Watch List" on the left. In that case do you propose it should change 
the display to select that program on the left instead of "All 
Recordings", as if I had gone to left arrow and selected the program 
name there? They may lose their place in the original "all recordings" 
list. Also apart from switching the list to the selected program it 
would have to make sure the same episode is still selected.

A program may have episodes in other recording groups. They would not 
display in this case.

What should it do if I already selected a program name on the left and I 
press right arrow? I suppose it would do the same, which would not 
change the list.

The right arrow pop up menu is not my enhancement, It is a change in the 
theme to use the "triggerevent" that causes the Menu to come up on right 
arrow. The MythCenter themes and most other themes have had this for a 
long time. Steppes only added this recently. If you want something 
different to happen we may have to persuade theme developers to change, 
or maybe we override the action in the theme.

Having the right arrow do different things depending on whether there 
are multiple episodes is not a good user experience. If the use is 
expecting episodes and gets a menu or vice versa it will be irritating 
for them.
