Hm, is that right? The transmitter at 704.5MHz has a different configuration
from all others? That's unusual...
There is a speciality with this channel decoder: If you define a parameter
like the GI, it takes this serious while many others ignore it.

And here we have the problem: as long as the firmware download is not
reliable, the board is unusable.
There must be somehing wrong with the board configuration.
In saa7134-dvb.c, line 744, please try to excange:
	.gpio_config   = TDA10046_GP11_I,
with
	.gpio_config   = TDA10046_GP01_I,
does this make the firmware load stable?

Best regards
