Does the sourcecap patch not address this whole issue? Even if source
cap or something similar is applied, how will VDR be able to tune to a
8psk turbo-fec type channel if v4l2 does not provide any support for
it? It shouldn't be VDR's responsibility surely? unless 8psk turbo-fec
becomes part of the new dvb-plugin archtitecture of future VDR.
