Umm, did you Google "Samsung T220HD"? If you did, the first 10 results give you your answer.
Uhmm... yes I did, and....... NO it doesn't.
The T220HD is listed both ways, with an atsc, and also dvb tuners. I'm trying to find out how to differentiate between the two, and have even been to the Samsung website. Samsung euro lists the t220hd with a dvb tuner, and all the american sites list it with an atsc tuner.
THAT'S what I'm trying to figure out. How to tell which one I have by the model number, or some other way.
After all the extremely helpful assistance here (insert extreme sarcasm smilie) I e-mailed Samsung directly, and they said that it actually had both atsc, and dvb tuners built-in. Seller had it listed as dvb only, but I took a chance it was atsc, and it paid off. I was having trouble getting my channels scanned, but I finally got it right, and all is well now.
