srp = by service reference, snp = by name.
The first has a one-on-one match between channel and picon, but means you may miss picons for other channels with the same name.
The second has picons by name, doesn't have that problem, but may show incorrect picons for some channels, and also has problems when you have renamed channels.
thank you for the explination,
is it that the different sizes are different screens ? or different skins ?
