What would cause stuttering frame rate and bad interlacing on local TV sub channel ?

New local subchannels are popping up all over, and most of them are stupid, crap filled wonders-- but one of them really stands out: every video stutters and skips frames (audio stays in sync tho, and doesn't stutter) and some ads look like low-res proxies...they aren't I've seen them elsewhere and they look fine. Any guess to what's causing this? First thing that came to mind was unnecessary pull-up or pull-down---They have 2.75Mbps bandwidth and we have 95% strength on our end.
The channel is 15.6 KFTB in Houston --704x480i signal. The guys running it are video shooters, not broadcast engineers...

2.75Mbps is a pretty low data rate...

E=MC2+/-2db

"KFTB 15.6," (a branding name- "Fort Bend County", not real FCC call letters) is a sub-channel of KVVV, a low power station which is running SEVEN sub channels, so the available data rates to each are by necessity extremely limited. Don't expect even fair quality Standard Def. over the air.
