I'm going to have to agree, unless someone else is running a Sempron 3100 and
able to do live HDTV I'm going to have to think this is the case. I know my
Athlon64 3200+ has no room to spare playing live HD, I can easily imagine a
Sempron of lower clock speed having more trouble.
LiveTV requires a bit more resources from mythbackend and mythfrontend from
what I've noticed.
