Problems getting MSI Mega Sky 580 to run

[feuera]

Hi,
I got troubles with a MSI Mega Sky 580
i have:
uname -a
Linux spike 2.6.18-gentoo-r6 #1 PREEMPT Sat Jan 6 09:47:12 CET 2007 i686 Intel(R) Pentium(R) M processor 1.86GHz GenuineIntel GNU/Linux

here is what I did:
from:
http://linuxtv.org/hg/~mkrufky/megasky
I downloaded the tree
make
make install (as root)

if I plug in now the device I get:
lsusb:

Code: Select all

Bus 001 Device 005: ID 0db0:5581 Micro Star International

dmesg:

Code: Select all

usb 1-4: new high speed USB device using ehci_hcd and address 5

dvb_pll                11460  1 dvb_usb

w_scan_start.sh loads lots of modules and finally finds channels in my area.
from w_scan I got a initial channel list which I used with dvbscan to get a channels.conf

tzap complained about syntax in channels.conf (don't know why)

Code: Select all

tzap ORF1
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/home/andi/.tzap/channels.conf'
ERROR: error while parsing constellation (syntax error)

dvb_streaming_read, attempt N. 4 failed with errno 0 when reading 1672 bytes
dvb_streaming_read, attempt N. 3 failed with errno 0 when reading 1672 bytes

with previous kernel I was able to tune. Xine always showed "buffering 50%" to "buffering 100%" but never showed one single useful picture. Mplayer had almost same behaveior.

any help appreciated.

thanks in advance

hi again

I found out that my problem was antenna polarisation.

I just wonder why windows was able to receive correct with any antenna orientation.

another thing:
nor dvbscan or w_scan are able to find any channel.
