I doubt that bandwidth is likely to be an issue. After all, DVB-T muxes tend to be something like 16 to 24 Mbps (depending on various factors) so even if you were slurping the whole mux, you'd struggle to go over something in the order 50Mbps - significantly less than USBs capacity of 480Mbps even allowing for overheads. What might be amore of an issue would be the reported USB driver issues - does anyone know if a) they were ever as bad as it was somtimes made out, and b) if the issues have been fixed ?
