You're talking about Dotcast, I take it.

The bit rate is 4.5 Mb/s in the 6 MHz channel, while also transmitting
NTSC, yes.


For Dotacast to work, they claim a need for a 40 dB of C/N. I can tell
you that I don't see that sort of C/N for any DTT channels I receive.

Sure, given enough power, you can increase the payload on any channel.
