The DVB core is completely different than the V4L core, and the hardware in question is also completely different. In this case you're talking about stats from the tuner; the pvrusb2 driver currently relies on the V4L core API (e.g. VIDIOC_G_TUNER) for such information. If it isn't available via that function, then it probably isn't possible right now to retrieve it. I imagine this isn't what you wanted to hear :-( -Mike -- Mike Isely isely @ pobox (dot) com PGP: 03 54 43 4D 75 E5 CC 92 71 16 01 E2 B5 F5 C1 E8 _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
