Here are the results from my "in depth" testing with a 500 with the
samsung tuners, post Hans' patch application to the 0.4.2 source tree.
I am seeing more or less the same results. Tuner 1 is "quality
deficient" still, but (inscrutably) tuner 2 is perfect on near all
of my available channels.
Here's what I did to test:
#!/usr/bin/perl
@channels = (2,3,4,5,6,7,8,9,10,11,12,13,19,20,22,23,24,62,63,64);
foreach $tuner (1..2) {
foreach $channel (@channels) {
$change = `ivtv-tune -d /dev/video${tuner} -c ${channel}`;
chomp($change);
print "channel $channel: $change\n";
`dd if=/dev/video${tuner} of=${tuner}.${channel}.mpg bs=1k count=10000`;
}
}
exit(0);
which produced output:
channel 2: /dev/video1: 55.250 MHz (Signal Detected)
channel 3: /dev/video1: 61.250 MHz
channel 4: /dev/video1: 67.250 MHz (Signal Detected)

I'm uploading the video content clips to this URL:
http://www.digitalcoven.com/ivtv/
(that may take a bit before they're all up there)
filename format is tuner.channel.mpg
I did ~15 second clips to make sure there is enough
content to visually see what is really going on, then
watched them all with vlc.
Again, tuner 1 is of much lesser quality, and the only
channels that are close to usable are the 7-13 or so and
the 19-23 are barely usable, and then 64 is good.
And then tuner 2 is great, but for channel 62, and channel
24 looks a little "not enough color".
And you can note from the script output, that on the first
tuner, it didn't even detect signal on channel 3....
Hope this is useful output for everybody. If you want/need
any more info, let me know.
I'll also inline the whole dmesg output of the card initialization.
