Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
    Tried with just modules that exist in kernel (no v4l-dvb)
   Tried v4l-dvb from June 2007 and tried current v4l-dvb
   Tried with/without Hartmut patch - changeset 7376    49ba58715fe0
   Tried with .gpio_config   = TDA10046_GP11_I, or .gpio_config   = 
TDA10046_GP01_I,
   Tried using configs in saa7134-dvb.c matching tiger, tiger_s, 
pinnacle 310i, twinhan 3056

    # Australia / Perth (Roleystone transmitter)
    # T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
    # SBS
    T 704500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
    # ABC
    T 725500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
    # Seven
    T 746500000 7MHz 2/3 NONE QAM64 8k 1/16 NONE
    # Nine
    T 767500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
    # Ten
    T 788500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE

2) I have these saa7134 cards:
    - pinnacle 310i
    - kworld 210

    This cx88 card:
    - dvico DVB-T Pro hybrid (analog tv not work)

-   problem only occurs with kworld 210 in linux (works fine in WinXP)

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan 
finds SBS - dmesg2

6) Herman mentioned something called a "mode-switch" in the archives, 
but not any description.
I tried to find some data sheets for tda8275 tda8290 but only found the 
publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" 
is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

What else should I try?

Regards,
Tim
