Sorry,but the skin is to see under Skins when I install it,but not to see under green button/red button/Skins and so only possible to deinstall via telnet,
Channel zapping is a little better,but two or three seconds for a Channel change it´s to much.
I used AJpanel to build .ipk file and I am not sure what is wrong besides the mistake in naming you mentioned. moreover; sure you will have some slow down in response related to posters loading/downloading...etc, I can send you any skin without posters. I'm sure it will be much faster.
Regarding the ipk, I can only repeat myself, if the ipk is OK, it will also be displayed under green button/red button/skins. If I put the ipk in the feed like this, it would not be displayed in the image feed. Try asking Lululla if he can help you.
It's clear that with skins without posters and backdrops everything is faster, but I can only say that with other skins that also use posters and backdrops the channel change is noticeably faster at around 1 1/2 seconds.
