I am trying to steam video to a D-Link DSM- 320 Media Center. I have some AVIs that will stream and some that seem to just hang the unit. For testing I am using 2 files, 03.avi and 04.avi. 03.avi wil work with no problems and 04.avi consistantly hangs the machine. I think that I have figured out a work around but it causes static (lines) when an image moves on the screen and I was wondering if I could as for some advice.

I used video inspector (http://www.kcsoftwares.com/index.php?vtb) and gspot (http://www.headbands.com/gspot/) to take a look at the encoding info for the files (below) they seem to be identical on the surface:

****Stream Works****
File Name : C:\test\03.avi
File Size : 328 Mb.

[Movie]
Valid : Yes [AVI]
Duration : 00:41:49
Movie complete : Yes

[Video]
Resolution : 640x432
Codec : XviD MPEG-4 codec
FPS : 25.00
BitRate : 904 Kbps
Quality Factor : 0.13 b/px

[Audio]
Codec : MPEG 1 or 2 Audio Layer 3 (MP3)
Number of channels : 2
Sample Rate : 44100 Hz
BitRate : 192 Kbps

****Stream Hangs****
File Name : C:\test\04.avi
File Size : 329 Mb.

[Movie]
Valid : Yes [AVI]
Duration : 00:41:51
Movie complete : Yes

[Video]
Resolution : 640x432
Codec : XviD MPEG-4 codec
FPS : 25.00
BitRate : 906 Kbps
Quality Factor : 0.13 b/px

[Audio]
Codec : MPEG 1 or 2 Audio Layer 3 (MP3)
Number of channels : 2
Sample Rate : 44100 Hz
BitRate : 192 Kbps

When I take a look at the AVI container info I did notice a difference:

File Name : C:\test\03.avi container info:
AVI v1.0
Audio frames: Aligned on interleaves

File Name : C:\test\04.avi container info:
AVI v1.0, "rec list" style
Audio frames: Aligned on interleaves

So when I search on " "rec list" style", I find several references to this being an encode option that allows easier indexing. I also find several references saying that this will cause issues with some players (specifically hardware bound players).

Now after doing some testing I can seem to use AVI-Mux GUI (http://www-user.tu-chemnitz.de/~noe/Video-Zeug/AVIMux%20GUI/) to strip the "rec list" style from 04.avi AVI container and it will stream but I seem to get static, what I am guessing are interleave lines, and the image does not seem to be nearly as clear as 03.avi. When I use gpsot to look at the codec info it now shows:

File Name : C:\test\final.avi
File Size : 331 Mb.

[Movie]
Valid : Yes [AVI]
Duration : 00:41:51
Movie complete : Yes

[Video]
Resolution : 640x432
Codec : XviD MPEG-4 codec
FPS : 25.00
BitRate : 914 Kbps
Quality Factor : 0.14 b/px

[Audio]
Codec : MPEG 1 or 2 Audio Layer 3 (MP3)
Number of channels : 2
Sample Rate : 44100 Hz
BitRate : 192 Kbps

Container info:

AVI v1.0
Interleve: 1 vid frame (40ms), preload 182
Audio frames: Aligned on interleaves Audio frames: Aligned on interleaves

So the question is, is there another utility that I can use to strip the "rec list" style or convert it to the standard AVI 1.0 format without modifying the interleave? My feeling is that AVI-mux is changing the interleave and that causes lines to form when an image moves on the sceen. Should I be using different interleave settings when I use AVI-MUX to eliminate the static problems? Thank you very much for help in advance!

Never had a problem here with AVIMuxGUI and the standalone profiles.
Interleave refers to audio/video interleave, not whether the video is interlaced or not.

Sorry about that. After some further research it seems to cause some interlacing after it has been run through AVIMUX.

If the video is Progressive before AVIMuxGUI, then it will be Progressive afterwards, same goes for interlaced. The actual video stream doesn't change.
