Around release 0.3.7f (algorithm) modifications were made to egalize

I never tried those releases after 0.3.7b(or d).
With the tagged 0.4.0 release I notice a big difference. The 350 is
twice as load as the 500.
I lived with the older 0.3.7 release, but I never noticed such a big
volume difference as with the 0.4.0 release.
I remember them well, since I made them :)
You're saying if you record the same content on both cards
simultaneously at the same volume settings (check ivtvctl -d (dev) -Y),
you get a different volume for each card? The code is there to map them
both to the same range, and in my objective testing they were the same
in recorded files. This is on a pvr-150, but it should be the same on a
500.
I noticed a difference:
[EMAIL PROTECTED]:/usr/local/bin> ./ivtvctl -d /dev/video0 -Y (PVR350)
ioctl: VIDIOC_QUERYCTRL
Brightness = 127
Contrast = 63
Saturation = 63
Hue = 0
Volume = 62225
Mute = 0
[EMAIL PROTECTED]:/usr/local/bin> ./ivtvctl -d /dev/video1 -Y (PVR500-1)
ioctl: VIDIOC_QUERYCTRL
Brightness = 127
Contrast = 63
Saturation = 63
Hue = 0
Volume = 61952
Mute = 0
[EMAIL PROTECTED]:/usr/local/bin> ./ivtvctl -d /dev/video2 -Y (PVR500-2)
ioctl: VIDIOC_QUERYCTRL
Brightness = 127
Contrast = 63
Saturation = 63
Hue = 0
Volume = 61952
Mute = 0
I don't set the volume. Is this the calculated volume from the driver, where
the value can be different to receive the same volume.
Do I have to set them to the same value.
