A few stb's reverted back to the RF channel number and showed the MPEG-2 Program number as the sub-channel (24-3 and 24-4). The LG-4200A, Zenith HD-SAT520, RCA DTC-100, Sony HD-300 and my own Samsung SIR-T165 had no problems at all. >2.

However, it looks like they got some help from the USDTV folks and the problem appears to be solved as of 3 pm Tuesday (and they are still using Program numbers 3 and 4). If I find out what the actual problem was, I'll post it here. A TVCT mismatch seems highly possible.
