From 8fb957841b2f4311e6418dcbef24564e4cebb87d Mon Sep 17 00:00:00 2001 From: Chris Pascoe Date: Thu, 10 Aug 2006 03:17:16 -0300 Subject: [PATCH] V4L/DVB (4495): Fix "no data from ZL10353 based USB tuner" problem Force parallel transport stream output on the ZL10353 attached to a bluebird device. Addresses the problem where a frontend lock was observed, but no MPEG transport data was received.
