Hi,<br>
vcr is a program which can grab and record an mpeg-4 movie from your tv
tuner card. It's a rather old one and it's writer has abandoned it but it
still works (some people ensure that it does). I encode with divx ;-) (that's
the name of the codec, including the winking sign !). Seems to work ok.vcr
supposedly can use other codecs too but I don't know how good that will be,
divx ;-) is supposed to be the best bet.It's actually a windows dll codec.AFAIK,
it is hosted at sourceforge.net.<br>
I am really busy these days at office so didn't get chance to run myth.<br>
I do have the kernel and bttv sources, I'll read the freeze file to see what
it talks about. Won' t have time for atleast two weeks though. Thanks a lot
for your helpful hints.<br>
<br>
regards<br>

<pre wrap="">Hi Dhiraj,
Don't worry, I didn't find your post rude. I don't know what this "vcr"
you speak of is, but all I can say is that there seems to be some problem
with Myth, possibly with the bttv drivers with this chipset.
Hope you can sort it out, and if you can, let me know what you had to do,
it just wasn't worth the huge amount of wasted time and frustration for me
in the end.
You might want to check out
/usr/src/linux/Documentation/video4linux/bttv/README.freeze, this might
help point you in the right direction (you need the kernel source for
this).
Best of luck.
Craig

<pre wrap="">Sorry Craig if that sounded rude ! I didn't mean it ! I am also thankful
to note that my card will not have any issues . Whew !
Craig, you do seem to say that I will still have issues but I hope you
are wrong ! I don't have the money to buy a new PC anyway !
I won't be running the test you want me to. I'm scared of what it might
prove :) I won't be able to correct the problem anyway, if it means
replacing my Mobo and processor.
So far I haven't had problems with any games or Mythtv. If I can't
record, well so be it. I'll just use vcr.
As you rightly pointed out, I do not understand how myth works. I have
never looked into the code. Just theorizing...
You seem to have said the same thing. My front and back-end are on the
same box, I watch livetv (not just playback), so in recording I am
actually doing "less" than what I would do in livetv.
Of course, I could be wrong.
I am sure there would be problems with KT133. Just hope they don't
surface for 1-2 years !!!
Thanks for telling me that the problem could be related to the HDD
writing. I won't increase my buffer from the current 1 GB. I wish I had
bought 1 GB more. It was just $25 for a 512 MB stick, in the good old
meltdown days.
So, you think myth wouldn't work properly while writing to the HDD when
it's recording. But then how does vcr work ??? It seems to write the
file without any problems.
The link you mentioned seemed to say that there are problems with nvidia
drivers and with heavy load on the PCI bus. I don't have problems with
the nvidia drivers, otherwise I wouldn't have been able to play quake
III and descent III . If I get problems with the PCI bus I will increase
latency to 64 instead of 32 (did you try that ?). It says this always
fixes the problem. My performance will go down of course, hope I don't
notice it !

I don't support your motherboard has a KT133 chipset?

I had the same symptoms, same CPU, and I bought a new 'puter to use,
booted up using the original hard disk, and haven't had a crash
since
If you have this chipset, I think that's your problem.
Hope this helps

<pre wrap="">I have the FIC AZ11E which also uses KT133 chipset. I have never had
kernel Ooops but my recording part is not working yet. If bttv has
problems with KT133 then why have I been watching TV for the last two
years using xwtv without any problems. How does bttv know that I am
recording or playing, it should be the same thing, this is just an
application level differnce. I have used the vcr program to record
shows in the past without any problems. If you can watch TV on this
chipset then it is perfectly possible to record too.
I am using RH 7.2 with AMD T-BIRD 950 MHZ
My mythtv recording part is not working because of some software
problem which I need to fix, it doesn't crash my machine. It just
doesn't record, nothing happens. I am not going to believe that this
KT133 bug surfaces only with myth and not with vcr !
A computer costs a lot of money. I can't afford to buy a new computer
because some particular feature of one application is crashing. Why
don't you use mythtv to watch live tv and use vcr to record in your
old computer. Should work on yours if it works on mine. If KT133 is
at fault, that is.
You murdered your old friendly computer :)

The problem with the KT133 chipset has nothing to do with bttv. If you
have a bttv card, as you seem to, then there is no issue. The problem
occurs if you have an ivtv card (PVR-x50, M-179). There is a known
chipset bug (or 'quirk', if you prefer) that causes problems when using
the ivtv driver.
Incidentally, Myth does not use 'bttv' for playback... since
playback-only in Myth doesn't involve the tuner card. The bttv/V4L
driver is only used in Myth for recording or LiveTV. Playback is done
solely through your video card using X (Xv/XvMC). So it is entirely
possible for problems to arise during recording that don't occur during
playback only.
Craig was only offering a helpful suggestion... there was no need to be
rude, especially since it seems you're not really clear on how Myth
actually works.
