MeTV isn’t a satellite network; it’s a channel feed that’s syndicated to local TV stations, for them to run on their secondary channels. This page on Wikipedia indicates that, in Little Rock, it’s on KMYA’s digital channel 49.1.
So, Comcast is picking up MeTV in the same way that it’s getting your other local stations (presumably, using an over-the-air digital antenna).
That said, as your local station is picking up their MeTV signal from a satellite, it’s possible that the issue is on KMYA’s end, rather than Comcast’s.
