On Time Warner, I have not seen any video issues on KVIA, just the usual audio stutter especially on local content. My complaint is that the CW is now in 16 X 9 SD (480i). I called the cable company and told them that the only two reasons I take the local channels from them is to get KRWG from NMSU rather than our sad PBS affiliate and to get the CW in HD. Amazingly, the service representative understood my complaint and at least said he would send a report 'further up'.
Also, while I have been gone, it seems Mynetwork programming from 6PM to 8PM on weeknights from KDBC-02 is in 16 X9 SD. It is not too bad and they have some good re-runs from recent primetime shows.
