It's possible, if the OP is using a ATV system, that the signal level
from the cable co. has dropped. Sometimes the level drops to the point
where the signal looks grainy, but some TV sets, with better tuners, are
still able to show a decent picture. In fact, it's the old "junker" TVs
that seem to have better sensitivity.
It's hard to think of anything that would cause a working Myth setup to
suddenly become "grainy", if nothing has changed, other than the
external signal or a tuner card problem. Just about any other hardware
problem would cause total failure.
