Does this mean that recording several channels at the same time from the 
same card (from the same transponder) doesn't work anymore, not even in 
theory? This would be a bummer, because it was one of my design goals to 
make that possible. Personally, I'd rather have Live-TV broken than 
multiple recordings. Multiple recordings currently don't work anyways 
due to MythTV, but maybe there is a better solution that will work in 
the future as well?
