Can't find ATSC channel after digital switch

[VCRUser]

After the switch, I rescanned, and lost channel 6 (WPVI-DT in Philadelphia), which I'd previously received. According to Silicon Dust, it's now on RF 6 (was 64), and the converter box attached to a TV using the same antenna receives the channel (it's somewhat weak, but there) and reports it at RF 6. Silicon Dust reports it at 6-3. I tried remapping in various ways: 6-6-1, 6-3-1, 6-0-1, but none of these work. Can anyone else receiving Philadelphia channels suggest the physical channel I should use? Is the channel just too weak for my 950s to pick it up, even though my converter box can tune it? My antenna leads are on an amplifier/splitter, and the other channels are working ok.

I lost a few when they switched the digital signal to the original VHF frequency. Before the final changeover they were on UHF. I have no decent VHF antenna. The difference might be the TVs ability to tune a weak signal.

Channel 6 (WPVI-DT in Philadelphia), appears to be a special case, see this post for more info. http://forums.sagetv.com/forums/show...1&postcount=15
