[mythtv-users] Ivtv - pvr-500 applying samsung patches

[David Fishburn]

Ubuntu Edgy
MythTV 0.20
Ivtv 0.7.1
Lirc 0.8.1pre2
Kernel 2.6.17-10-generic

This is my first Myth box.

I have a Hauppauge pvr-500 with samsung tuners.
I have been trying to compile my kernel so that I can apply the samsung
patch but I keep getting errors:
...

I found some information that the 2.6.17 kernel doesn't have the updated
changes to make the samsung tuners better.  To put that in I need to compile
the kernel.

I thought I would describe what I see to make sure everything else it up to
snuff.

    ivtv-tune -d /dev/video0 -c 42
    cat /dev/video0 > /tmp/test.mpg 

If I use low channels 2-5 it is nearly unviewable.  All snow.
If I go high, 42, still quite snowy, but I can actually recognize what I am
watching with colour.

If I flip over to the second tuner:
    ivtv-tune -d /dev/video1 -c 42
    cat /dev/video1 > /tmp/test.mpg 


Then it is always snowy on all channels.  The higher channels I can sort of
make out that it did record what I can see on the television.

I have split my cable input with a radio shack splitter.  How much
interference can result from this?
