I don't know of any major cable companies that broadcast atsc (8VSB) on their systems. We only use 256 QAM at the company I work for (Time Warner). We take the stations 8VSB signal and send it through our equipment and convert it to 256QAM. Two reasons why we do it that way as noted our digital boxes can only receive QAM and by us using QAM we can almost double the data rate to 38 Mps for each 6Mhz channel. 8VSB can only do about 19 Mps.
On a different note I went to Wal-Mart today and picked up my two converters (RCA DTA800). I also purchased a set of rabbit ears because I don't have an outside antenna at my home. My only problem was they had no idea what to do with the coupons took 15 min before they learned how to process them.
Took me 10 min to get one of them running in my office with my roundie the thing even works well with poor signal levels from the rabbit ears. At my headend we are using a big UHF antenna for our older 8VSB receivers this little thing works much better then the $2000 boxes if only it had a digital output. I hate to say it but this cheap converter really changed my mind about the whole off air digital conversion thing.
