[linux-dvb] controlling the dvr device

[Ingo Krabbe <i.krabbe@dokom.net>]

Hi,

I'm trying the following please correct me if I made some errors:

A) compiled and installed the newest snapshot of the dvb drivers with
   'make insmod' which gives me following module layout by 'lsmod':

Module                  Size  Used by    Tainted: P  
dvb-ttpci             294548   0 (unused)

videodev                5312   0 [dvb-ttpci]
[...] other modules 

The 'dmesg' command for kernel messages tells me:
Linux video capture interface: v1.00
DVB: registering new adapter (TT-Budget/WinTV-NOVA-S  PCI).
stv0299.c: setup for tuner BSRU6, TDQB-S00x
DVB: registering frontend 0:0 (STV0299/TSA5059/SL1935 based)...

Which is completly ok for me and my devfsd has registered four devices:
/dev/dvb/adapter0/frontend0
/dev/dvb/adapter0/demux0
/dev/dvb/adapter0/dvr0
/dev/dvb/adapter0/net0

B) I'm trying to tune a channel with 'szap -n 001' with the following output:
zapping to 'Das Erste':
sat 0, frequency = 11837 MHz H, symbolrate 27500000, vpid = 0x0065, apid = 0x0066
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 1f | signal b039 | snr cb0d | ber 00005a00 | unc 00000000 | FE_HAS_LOCK
[...] lots of similar lines

ok I think thats fine.

C) so I try to read from dvr0 but ...... nothing ???

What do I need to do to get some output from dvr0 (or somewhere else) know ?

TIA INGO
