No. Both w_scan/dvbscan get the same channels, and they match the channels available at the STB and with other boards. Btw, drivers/media/common/tuners/xc5000.c doesn't support 7MHz for DVB-T: case BANDWIDTH_7_MHZ: printk(KERN_ERR "xc5000 bandwidth 7MHz not supported\n"); return -EINVAL; This may explain why you're getting so few channels on it. Only channels marked as 8MHz will be tuned. I _suspect_ that: case BANDWIDTH_7_MHZ: case BANDWIDTH_8_MHZ: priv->bandwidth = BANDWIDTH_8_MHZ; priv->video_standard = DTV8; priv->freq_hz = params->frequency - 2750000; break; would be the right thing to do.
