The USRP could receive the raw signals for DVB-T in the 6 and 7 MHz wide channel format. The 8 MHz wide version could be somewhat degraded because of filter rolloff at the edges of the passband of the digital downconverter in the FPGA. Shifting to 8-bit I&Q would allow the full 8 MHz wide signal to fit across the USB at the expense of dynamic range. I'm not sure of the bandwidth required for DVB-S and thus can't comment.
