Hi!

Thanks, this is clear now.

The 300i should be able to do analog SECAM-L,
but I guess it won't happen within one day and there is no reliable
detection of sub-tuner types on the saa7134 driver.

It hits in the middle of some likely still unknown,
but is not restricted to video _and_ audio SAW filters.

As far I remember, the audio carrier is minus 40db to the video carrier
on SEACAM-L. Doesn't tolerate any wrong settings and drives the chips to
their limits.

The SAW filters are outside the tuner housing on mt2050 types and there
are tables ...

In this case "works on windows" or 2.6.12 compared to recent is
accepted ;)

Cheers,
Hermann
