Subject: [BUG] TDA10086 : Creatix CTX929_V.1 : TS continuity errors with good RF signal input
Date: Fri, 26 Feb 2010 15:39:30 +0100	[thread overview]
Message-ID: <4B87DD22.3000209@gmail.com> (raw)

Hi, 

Issue is already confirmed here:
http://www.vdr-portal.de/board/thread.php?threadid=93268

Linux 2.6.32.8, 80cm dish.

Do we have any Tuner/Decoder optimization points in the FE code?

This is not OK:

lspci -s 00:08.0 -v 00:08.0 Multimedia controller: Philips Semiconductors SAA7134/SAA7135HL Video Broadcast Decoder (rev 01) Subsystem: Creatix Polymedia GmbH Device 0005 Flags: bus master, medium devsel, latency 32, IRQ 19 Memory at fbeff400 (32-bit, non-prefetchable) [size=1K] Capabilities: [40] Power Management version 1 Kernel driver in use: saa7134

Low signal strength values are AGC-loop misinterpretation as usual?
