Glad to know I'm not the only one having this problem.  I saw the thread
from John Williams about something similar, although his description was
that he was getting static, and in his logs he was having problems with the
eeprom module not loading correctly, which I've looked for and do not have.
I only have one tveeprom module and according to the logs it's loading
correctly.  

It is exactly as Richard describes where I can specify a channel to tune to
and it gets it close enough so that if I'm watching carefully I can kinda
see what the program on is between the flipping and vertical bars, and
indeed it's the channel I specified.  I always thought that the frequencies
were a good guess for the card since they might be slightly different for
each person and it was the job of the hardware tuner to take that guess and
get to the closest good frequency, which it apparently isn't doing.  Even
manually passing frequencies to it using ptune.pl seems to get the exact
same result unless I pass it a value far enough away from the correct
frequency to get complete static.  It's almost as if the tuner is homing in
on the correct frequency plus an offset, so it never gets tuned in
correctly.

I'm going to try the card in a windows box tonight to see if it is indeed
hardware related, but somehow I'm doubting that since it worked fine before
and all I did was move it between two boxes.

I'll also take some pictures of it during the move so that we can see if
we're talking about the same card.

Subject: Re: [ivtv-devel] Older PVR-250 card not tuning properly

Not just you, I also have the same issue on an older 250 with tuner type 2.
I had a camera on order to send in some pictures of the card per a request
on this list, but just finally got it.  I had been suspecting something
physically happened to my card in the time it was unused, but your post
definately makes me think it's something that changed in the driver now.  My
next window to get the card out of that machine is tonight.  I'll get off my
butt and send in the pictures and the rest of the debug info ASAP tonight.

Btw, I bet your tuner mostly follows the stations correctly if you give it a
shot.  Ie., 46 is 46, just slightly scrambled, etc.  This wouldn't likely
happen if your card was using the wrong frequency standard (at least not on
a good sample).
