KBTX (Ch 3) in Bryan - College Station is the CBS for this area (Ch 10 is for Waco but we also get it).
It says it is in HD, the feed is the HD feed (says HD on the logo and I get the same feed OTA in HD) but it is streaming in 480i. Directv must be expecting the feed in HD as the guide also shows which shows are in HD etc.
So it should be in HD but isnt.
KXXV (Ch 25) is the local ABC affiliate for Bryan - College Station an is in HD
KRHD (Ch 40) is the local ABC affiliate for Waco and has the same problem as Ch3 above. It says it is in HD, the feed is in HD but it is showing up in 480i on the receivers.
