Hi,
here I am back again with the same old story (someone should remember
the "zig-zag pattern" thread some months ago...)
I had no time to make new attempts to capture with my DC30+, but now I
have a little, so I wish to try again. Yet, I know the problem is still
there, so I'm looking over t

What do you mean exactly? Is there some v4l configuration I should
check? Where is this filter set up?

Dear
Hi,
both my miroVideo DC30+ and KWorld DVB-S 100 capture card show on every
frame a strange pattern that I never got before. I say zig-zag but I'm
not sure is the right expression. The best way to understand what I mean
is watching it with your very eyes.
I can provide a very short sample, but

Hi,
I just bought a DVB-S card which also has an analog input and is
perfectly recognized as a v4l2 card. It works with xawtv, though with a
slight problem that eventually will be the subject of another post, some
day.
I understand, if I'm not much in error, that lavrec should work with v4l

Yes, I can record, but the resulting images show a zig-zag pattern that
probably can be explained with what you say below: the signal is
actually composite video, but it goes into a S-Video
Dear all,
at last I can capture again with my DC30+, but using a S-Video cable
only. As Bernhard suggested, the RCA connector of the card must be
damaged, while the S-Video connector works fine.
Well, not as fine as I wuold like, I must say. The pictures I get, if
one looks very close, show a

Hi!
I've using my DC30+ very intensively for a long time, until yesterday:
in fact, today it's not working any longer.
The kernel seems to be aware of it, as usual, but when I start xawtv I
get a black screen and the following messages in dmesg:

I finally disabled the on-board sound card and got back to my old

Hi!
Recently I had to change the motherboard and since my PCI sound card is
very old (Ensoniq 1371), I decided to use the on-board card (C-Media,
alias AC'97, alias Intel ICH5, I don't know exactly what it is). It
works fine, but when I try to play some AVI file I recorded with the old

Hi,
I'm capturing an old Video8 tape at decimation 1, as I always do. Quite

I have a rather old Ensoniq 1371. It has been working fine for many
years, though it seems not able to sample at 48KHz. This has nothing to
deal with the subject, I guess.

Hi, everybody!
Some month ago, someone on the list, I guess Stephen Shultz and others,

At last I bought it, brand new, just the model is CT2, not CT200, but

Here are the facts.

Hi,
first of all many thanks to Bernhard and Steven for their help about my

I'm still here with a question about lost frames. Stated that I probably

Hi,
has anyone of you ever seen the above message from lavrec?
I never saw it until I upgraded my Ubuntu box from Breezy to Dapper. I

related to a wrong field order in PAL sources).

them digitally the best way.
