There's nothing at the DVB core returning -ENOSPC.

Try to add just one line to a channels file, like this one:
	C 602000000 6900000 NONE QAM256

(this is the transponder that failed with w_scan. You could also use one
of the transponders where you got a pid timeout with scan)

Then call scan with this file, using strace:

$ strace -e ioctl dvbscan channelfile

This would allow to see what ioctl returned -ENOSPC (error -28).
