From 853ea132c75ff2c4e3c3aaf61bf3ef5779774dbc Mon Sep 17 00:00:00 2001 From: Soeren Moch Date: Fri, 25 Jan 2008 06:27:06 -0300 Subject: V4L/DVB (7070): Fix some tuning problems The attached patch solves all my vdr tuning problems on a dib7000p nova-t stick as far as I could check within the last weekend. It disables streaming while tuning, like that the number of faulty TS packets is reduced.
