From my experience, The pound signs are used for channels that have no PSIP data (or are too weak to accurately read the PSIP data). Channel 7 and 13 are VHF and you may need a different antenna. I'm also in Southern California and KCOP-DT (13) and KTTV-DT (11) are currently broadcasting at lower power, so that may also be contributing (although I'm 105 miles from their transmitter and still receive them).
The "no tables" shows up because there still are stations broadcasting on channels 2,4, and 5, but they are analog. Analog stations have no PSIP tables.
