for all those who are wondering what is going on with the terrible pq on hd digital channels.....
this past wednesday time warner came out to my apartments and replaced all wiring. The tech told me that the wiring hasnt been replaced in over 14 years. I asked him if this was normal, and he told me he would be willing to bet that the majority of columbia has not been updated in over a decade. He also said that all a customer has to do is call and ask when the last time the wiring was replaced and if its been a few years to request to have them replace it because of the terrible pq.
another thing he told me was not to worry about time warner saying no. they wouldnt do that unless the wiring is pretty recent. Just tell them that you are willing to go else where if this is best pq you are going to get with them (he said thats what his neighbor did)
but anyway, back on point. After wednesday my pq looks great, i mean crystal clear. Another thing i have noticed is that my internet speed has also gone up. Before i was looking at 4.2-4.8 mbps. After wednesday i am between 6.2-6.7
hope that helps you guys. Very satisfied after the replaced wiring
