most of the time I don't see many artifacts on digital cable... some channels are worse than others. Here's what pisses me off about it: I seem to go through boxes like water. On Time Warner I went through 2 boxes before I got mad and cancelled. Now my Wideopenwest box is acting up. Tonight it just turned off and wouldn't turn back on.
However, I really don't like DirectTV at all. I saw way more artifacts with DirectTV, and the channel changing CRAWLED. At least when you hit the Info button on digicable it comes up right away, on DirectTV you just wait... constantly. And I don't care what they say about weather not affecting directTV... it goes out at least one a month, always when there's a big rain storm or snow storm. However, I think it's back to analog for me. I've had it with having to use these POS boxes for not many worthwhile channels.
