list defaults

Hi Alan,

can't we have the list defaults back, like it was previously?

Means, everyone is just replying to the list and all other is a private
decision, out of what ever reason.

This would avoid at least, that mails with totally unacceptable content
can reach one privately only, because they are filtered on the list.

You don't even have the chance to show, that something really strange
did hit you, since you can not even quote it, because for good reasons
it never makes it through the list's filters.

Cheers,
Hermann

My, that is the usual since ever before global silicon tuners did
appear.

It is even far below Philips ME MultiEurope MK3s, 4s, 5s ...

Nothing to check there, old very well known chips are in there baked
together with some "other" discretes including the poorer home brewed
SAW filter.

Hi Hans,

Here is a new YVYU decoding patch which replaces the previous one.

Sorry for it is not tested: the webcam 046d:0896 does not work well.

Cheers.

You are right. PCI is only faster for transfers of 4 bytes or less.
The throughput formula for memory writes without waitstates on PCI is
  400/3*x/(x+8) MB
and for memory writes with infinite credit without ECRC on PCIe
  250*x/(x+20) MB,
where x is the burst size and must be a multiple of four in both
protocols.

The equilibrium pattern for latency values between 20 and 254 at a
trigger of 4 in my simulation is the same.

Yes

I have a device with similar chips. All of them are supported. TNF9533-D is PAL, afaik.

Took me forever to figure that out!

It is possible to add some autodetection for it. Are you using the driver at
http://linuxtv.org/hg/v4l-dvb, right? On its dmesg log, it will print some codes that helps to do some
tricks for detecting it, based on I2C scan signature.

> The problem arises when I try to do anything with it, though: I've tried a few programs, including mythTV,
tvtime and xawtv. I can't find a way to select the TUNER as the input source. The only options are
"composite1" or "s-video1".

It seems that you're selecting a different board type.
