[mythtv-users] PVR 500 defective?

[Danesh]

Cory::

Both tuners seem to initialize.


Dave::

Under /lib/modules I have

-r--r--r--   1 root root 369K Sep 27 23:07 HcwFalcn.rom
-r--r--r--   1 root root  14K Sep 27 23:07 HcwMakoA.ROM
lrwxrwxrwx   1 root root   25 Sep 27 23:07 ivtv-fw-enc.bin ->
/lib/modules/HcwFa

md5sums

5f5fa240ada73c3565f5f7de4c7b5138  HcwFalcn.rom
3a4803384f749d644ee1f1ca9dcb12fa  HcwMakoA.ROM
5f5fa240ada73c3565f5f7de4c7b5138  ivtv-fw-enc.bin

I will try downgrading the firmware to an older version. Is the
0x02040011 version the one on the CD?

I can access both tuners fine. Only one gives me nothing but static. I
don't know if this is related to a 'vbi: Invalid argument' I get on
the terminal when mythfrontend is running.


Greg::

Thanks for the pointer. I had it setup this way already. The capturing
Im trying to do which is giving me static is using ptune and cat
/dev/v4l/video0 > ~/vid0.mpg. The tuner0, tuner1, s-video0, etc
doesn't come into it.
