b) With more recent kernels (3.4 and 3.12, I think anything higher than 3.0) I'm seeing regular dmesg events like so
usb 1-1.2: dtv_property_legacy_params_sync: doesn't know how to handle a DVBv3 call to delivery system 0
I'm not sure what causes this (no other errors), but it's related to the older DVB-T receivers. VDR is built with the same kernel/DVB as the machine it runs on. Is this just a driver issue, or is there a test VDR could/should do based on API to avoid making the unhandled DVBv3 call ?
I would assume this question is more appropriate for the linux-media mailing list. Driver issues are better fixed in the driver rather than workarounds in an app imo.
