I'm not sure what FE_CAN_QAM_AUTO is supposed to represent exactly so the problem may not be in VDR, but rather your cards driver not accurately reporting it's capabilities. In which case, the driver needs to be fixed of course.
The card is a Twinhan DST DVB-T using the bttv driver. I'm not an expert at reading kernel source, but in drivers/media/dvb/bt8xx/dst.c it does seem that FE_CAN_QAM_AUTO is unconditionally set. The card documentation doesn't specify whether the device can in fact handle all possible QAM settings.
