[linux-dvb] szap/driver problems

[Thargor <thargor@vergessene-welt.de>]

Hello

I have some problems with the new driver version, szap, vdr-1.1.x

Old driver, szap and vdr-1.0.x works fine, beside i can't see the
video/audio output direct, because i dont have a TV, but i can record and watch the
files with mplayer.

Card: KNC1 DVB-S Tv-Station
Chip: SAA7146AH

Problems:
vdr-1.1.x 
- don't get any epg-data
- recordings end after 3 sec, files have 0 byte and vdr stops without
  warning

- channel switching works!

but...

szap:
./szap 'ProSieben'
zapping to 'ProSieben':
sat 0, frequency = 12480 MHz V, symbolrate 27500000, vpid = 0x00ff, apid = 0x0100
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

but nothing happens... 
messages shows the following:

and so on
Press STRG-C stop szap with Segmentation fault

start szap again:
opening frontend failed: Device or resource busy

driver/make rmmod fails: 
alps_bsru6: Device or resource busy
dvb-core: Device or resource busy
videodev: Device or resource busy

but no dvb-s application is running.
