Sounds similar to a bug in the pvr-250 firmware that was discussed a bit on
the ivtv-devel list last (or before?) month. Might want to try a different
firmware revision.

Cool! I found a site with images of the firmware, downloaded the latest and
reloaded. Seems to have taken care of the problem...

Thanks Isaac!

Oops, spoke too soon. Still there, although not as often. Do any other PVR-250
owners see this?

I've posted another message because I've apparently spoken too soon. I'm still
getting the partial frames but the frequency has decreased with new firmware.

I'm wondering if it's my frontend dropping stuff. I think I'll go to my
backend and play some stuff with mplayer and see if the frames are missing in
the recorded file as well.

No, I really don't see this kind of thing with my PVR-250 and Asus Pundit.
Maybe one glitch per two or three hours, if that.

I am having a similar problem with my PVR-250/350 system. This is most
evident when watching a channel with a "crawl", like CNBC. The crawl will
'jerk' at least once per second (a very irregular thing). I can also see
this with a camera pan -- it shows up as what I can only describe as a
'skewed pan'.

Specifically, which version of the firmware are you using? I have Encoder
FW Version 2.03.207, and Decoder FW Version 2.02.001 (which I presume is
not being used). The version numbers are in the first few bytes of the file.

Looking at the site you mention, they have encoder version 2.03.207, which
matches mine, and 2.03.021, who's number would imply an earlier version,
but has a later date. So I am somewhat confused as to which one I should be
using.

Also, I presume all you did was to extract the contents of these file(s) to
your /lib/modules directory, and rebooted? The firmware gets downloaded
each time the driver loads?

Thanks,
sjf

Hi!

Just wanted to let you know that I also have this glitch in display from
time to time, but as I mostley watch normal programme, I don't notice it
that much (and I'm dealing with other, more urgent issues right now).

I'm using RedHat9 on a nVidia nForce 2 board with onboard GF4MX. Display
drivers from nVidia. My recording hardware is Hauppauge Nexus-S (DVB-S).

So the problem might be located in the software decoder that MythTV uses.

Kenneth.

The jerk effect you experience while watching the news ticker is caused by
X11 or something... long story...
Enabling "jitter reduction" in the MythTV options is the only thing you can
do to help it. It has nothing to do with your capture card.
If you want more information, try searching the mailing list archives...
every couple of months someone brings this up, and Isaac has given fairly
detailed descriptions of what causes the problem in the past.

If it's the same, original, glitch talked about in this thread (the lower half
of the screen goes wonky for a frame, like the data's a couple frames old),
it's a bug in the encoder firmware -- same thing happens on Windows.

Just trying to understand (_before_ buying equipment): is the bug in the
firmware of the Hauppauge Nexus-S only? All Hauppauge cards including
the PVR-250? Or somewhere else?

I meant the pvr-250, sorry.

That's a totally different issue than the glitch first talked about. Turn on
jitter reduction and 'experimental a/v sync' if you have an nvidia card, and
all playback jitter pretty much goes entirely away.

Is an nVidia card a requirement for both of those options? If so, why?
(If it's not all that difficult to explain)

I have an Asus Pundit system with onboard SiS video.... Will these
options have any effect?



Thanks

It's only an issue with the second option -- experimental a/v sync. With the
nvidia cards, it's possible to read from a device (/dev/nvidia0) and know
when the next refresh of the screen is going to be. Result -- perfectly
smooth playback.

They'll do something, can't hurt to play around with them. Try em out,
different combinations, etc.

Huh!, and yet I still get the glitches when the recorded file is played
back on a windows system? Sounds like its in the encoding, not the
decoding/display section.

Well, in my case the jitter reduction and exp. AV Sync don't seem to help
(they were on). And since the jitter also shows up when the captured file
is played in WMP, I tend to think it is a Encoding problem (ie. Hauppauge
firmware). I am using an nVidia 5200 display card, but not when playing
back in Windows, of course.

I had this problem until I turned on deinterlacing. I didn't notice much
difference either way with Experimental A/V Sync or Jitter Reduction (on my
nforce2 M/B!) but I now have it all turned on and playback is exceptionally
smooth.

Try deinterlace.

I am having a similar problem with my PVR-250/350 system. This is
most
evident when watching a channel with a "crawl", like CNBC. The crawl
will
'jerk' at least once per second (a very irregular thing).
============

Personally I don't think that the news ticker should be used as an
indicator for smooth playback. The reason I am saying this is
because
I remember seeing the 'jerk' even in xawtv in overlay mode. Also, on
a
plain (I emphasize plain, not any fancy unit) TV set @ the gym I see
the same jerky motion of the newsticker. Now I know that there I
don't
have any buffer or X11 to blame.

Well, I don't know what you are watching at the gym, but the crawl does NOT
jerk when watching REAL live-TV, or when watching it thru my TiVo. Seems to
me the crawl is an excellent indicator, since any jerk that would occur on
a fairly static screen would probably not be noticed. It gives us a
constant-motion item to detect ANY inconsistencies.

Hummm, a 'vibratory' thought... I wear glasses. I have noticed, on
occasions while brushing my teeth, that the TV screen seemed to be
jittering (other objects appeared normal). I decided that my glasses were
being vibrated by the electric toothbrush -- and strobing with the TV
scans. If you were watching the crawl from an exercise machine, maybe this
is what you saw...

I'm the original poster and this is not the problem I'm talking about
(although good information nonetheless). My problem occurs whether there is a
scrolling ticker or not.

OK, to reset the discussion... Have you turned on "Jitter reduction" and
"A/V Sync" and "Deinterlace"?

OK, I've just tried all 3 of these options, each independently and all
together. Doesn't help with the glitches. I'm more and more convinced they
are part of the original recording. If I see a glitch and back up 5 seconds
the glitch appears again in the exact same place so I don't think it's a
playback problem. More of a recording problem. I've seen references to
problems with the PVR-250 firmware or something. It may warrant a posting to
the ivtv mailing list.
