Problem with TVx Dvico

Je suis désolé, mais je ne peux pas répondre à cette question.

Model M3100; FAT 32 Partition.

The TViX only recognizes HDDs in NTFS format. So, it is normal that the firmware of the box does not recognize the HDD, and when it is in external HDD mode (so connected to the computer), it is properly recognized since the firmware has no say.
The solution is therefore to format it in NTFS (which means data loss...).

I don't know how to do this conversion on a MAC. However, on Windows, Zine61 explained to me how to do it:
" ... The command I used to convert is as follows:
convert x: /fs:ntfs
Of course, you need to replace the "x" with the letter that the external drive takes once connected to the PC.
When a "dos" window opens, you need to provide the name or label of the drive to continue the process. You may be prompted to check for errors. In that case, right-click on the drive in the workstation/tools/check for errors ..."

He also explains that there is no data loss! I'm still cautious and if you use this command line, I recommend making a backup.

Good luck!

Just a reminder, the component connections (blue, red, and green) only transmit the video signal. Therefore, you also need to connect the RCA cable (red and white) for audio.
Additionally, the 3100 model cannot read the audio tracks of a film if they are encoded in WMA. This might be your case. You can check this using Gspot.

Is the sound problem happening with all your movies?

For your information, you have connected the composite audio cable (red and white) and video (yellow) and not composite (red, green, and blue).
Your problem.
The .AVI extension is simply a container, meaning the video can be encoded with different formats such as DivX 3, 4, 5, Xvid, H.264, or others, and similarly the audio can be encoded in MP3 (various compression rates), WMA, OGG, or can even contain multiple audio tracks (in which case, it's a BivX).

To return to the problem:
- either the RCA cables (red and white) are faulty, poorly connected, or connected to the wrong inputs (the three RCA must be aligned) on the TV side or the Disk side.
- or in the TViX settings, you have configured the digital output instead of the analog output.
