From 2f2710bd4ee11a06e4c87956be4733566e288a2e Mon Sep 17 00:00:00 2001 From: "Igor M. Liplianin" Date: Tue, 25 Jan 2011 17:08:00 -0300 Subject: [PATCH] [media] cx23885, altera-ci: enable all PID's less than 0x20 in hardware PID filter It takes too long time to scan due to low symbol rate PID's like PAT, PMT, CAT, NIT. For that matter we enabled permanently all PID's less 0x20 in hardware PID filter for NetUP Dual DVB-T/C CI RF card to combine rates. Signed-off-by: Igor M.
