Help with m2v files

[Mikhel]

Hi, I have a satellite receiver (Openbox S9) which uses M2V files as background for when it is booting up, it can be changed by a personalized background (called boot_logo.m2v), it has to be of a certain size (in pixels and in kb), in the past any 720x576 m2v file from 30 to 40 kb worked, but now they changed something and i can't seem to understand what it is, because as far as i have checked, the boot_logo that comes by default in newer firmware updates (which are needed because they fix stuttering in high bitrate HD channels) seem to be the same as the older firmwares (up until July 17th).


Here is a capture of the July 17th boot_logo.m2v file:

I tried to create one and when i flashed it on the receiver when it booted it displayed it fine, but once the receiver showed video the image was displayed as "garbled", badly distortedn whenever i turned it on or booted it again. Then i reflashed it once again and disconnected the "satellite in" cable to not allow the receiver to show a picture, and whenever i turnet it off and on again or booted it up, the image displayed fine, I allowed the receiver to again display video and the picture became distorted LOL.

I tried to contact the guys who make the receiver but they're in China and never answer, well, one time they answered and told me their engineer didn't know.

This is the info from the file i made (if i encoded it as interlaced the receiver rejected it):

General

Any idea on what else is different besides one being progresive and the other being interlaced? When i used the progressive in the July 17th firmware it was updated fine and it works, when i used it on the newest firmware it became distorted, I thought they had coded the size of the boot_logo.m2v so it could only be replaced by one of the same size, but since they publish the same firmware with two different boot_logos of different size (same specs), when i interchanged them, they worked, so, it was not the size and i don't know how to get this part when encoding an image to a m2v file (TMPGEnc misses one line):



Original:
Scan type : Interlaced
Scan order : Top Field First
Compression mode : Lossy
Writing library : MPEG-2 Test Sequence, 25 frames/sec
Color primaries : BT.470-2 System B, BT.470-2 System G
Transfer characteristics : BT.470-2 System B, BT.470-2 System G
Matrix coefficients : BT.470-2 System B, BT.470-2 System G



TMPEGEnc gives me just:

Scan type : Interlaced
Scan order : Top Field First
Compression mode : Lossy
Color primaries : BT.470-2 System B, BT.470-2 System G
Transfer characteristics : BT.470-2 System B, BT.470-2 System G
Matrix coefficients : BT.470-2 System B, BT.470-2 System G

This being the interlaced m2v file that the receiver rejects.



Same info but side by side:

Thanks in advance.
