Hello there,

I just recently finished an encode of Star Trek Nemesis with Xvid (Koepis Build from 24.6). Options were:
Motion Search Precision: 6
Quantization type: H.263
FourCC Used: DIVX
VHQ : 1
Maximum I-Frame Interval: 500
Minimum " " : 5
Chroma Motion enabled
Quarterpel disabled
GMC disabled
Max B-Frames : 2
B-Frame quantizer ratio: 150
" " offset: 100
" " threshold : 0
DX50 B-VOP comaptibility enabled
Chroma Optimizer enabled
Trellis R-D disabled.

Final Resolution was 720x304

The problem is now: Whenever I try to play the file, I have a blinking green line in the lower right corner. I use ffdshow for playback and already tried all the IDCTs it has to offer, tried setting libvibacodec and Xvid in the Codec-Settings and changed FourCC to DX50 and Xvid but with no luck. Funny thing is: When I enable cropping in ffdshow and crop 16 lines from the bottom, the blinking green line remains in the now black bar.
When I load the video in VD, there is no green line, so it seems like the problem is within ffdshow.
Only solution so far is to completely disable the decoding in ffdshow and to use the Xvid Decoder, but without any of ffdshow's postprocesing options then...
I discovered that this problem was discussed earlier
here (http://forum.doom9.org/showthread.php?s=&threadid=55233), but apparently no solution was found.
Can anybody help?
Oh, almost forgot: I use the ffdshow build from 16.08.2003

Edit:
Also forgot to mention: The blinking green line only appears in full-screen mode.

First, make sure you have newest video card drivers - try different ones if you can.

If this doesn't help, go to ffdshow's configuration and under "info" tab, find out what colorspace is used. Disable it in "codecs" tab, then try again (ffdshow will use a different colorspace). Should help.

Yikes!
Sorry that it took me so long to answer!
Had a shitload of work to do and after that I simply forgot this thread.
Anyway: Disabling YV12 under the "Codec" options solved my problem. Thanks :)

I had a similar problem some month ago.

The problem was that horizontal resolution was not mod32, only mod16.
Some video cards have problems if the video hres is not mod32.
If you want video at max resolution, use 704 (i crop 8+8), not 720.
