What receiver are you using? As Brian says, it should be OK (as long as it does DVB-S2 and MPEG4/HD).
There has been a substantial loss of channels since your installation. For example, just in the last three years G19 has gone from 18 transponders down to 13, and from around 200 channels down to around 140. So there has been much movement/loss.
As Brian notes, if you haven't been keeping you channel list current (by blind scanning and removing channels) then your list will be very outdated, and needs to be completely re-done.
The only other Ku satellite with a lot of foreign language channels are those at 30W, so if you wanted to add those, you would need another dish.
