My mom's THD upgraded from 9.4 to 11.0 yesterday, and in turn lost about 10 HD channels in the process. TBSHD, TNTHD, CNNHD FoodHD, etc...from ch 720-732 (BH in Pinellas County, Florida). Called BH and they said it's an "area wide problem," but they're sending out a tech w/a new M-card tomorrow after trying re-hits on the card several times today. Now the THD is prompting me to 'rerun guided setup,' which I'm now doing ...but I doubt this will cause the missing channels to come back. Still getting HBOHD, ESPNHD, and all the local channels in HD....and this thing has been up and running flawlessly on the M-card for almost a year. Any other BH customers have this problem with losing HD channels?
