    Default Canīt modify transcoding size. Just outputs 720p

    Hi i wanted to know i chan i change the max video size. In the software is not working. I tried in Media Server/Media Devices/Edit Device:

    - General: -Connection Ethernet 100 mps
    - Device Profile: Sony Bravia KDL (the most similiar to Sony Blu-ray i think)
    - Transcode incompatible media files

    - Performance: - Maximum video size: 720x405
    - Video bitrate: Less Quality

    - Advanced: - Default Settings

    Media Server/Trancoding Settings:

    - Maximum folder size: 100 Gb

    - Transcoding CPU priority: Normal

    - Maximum number of audio/video transcoders: 3

    - Complete partially transcoded audio/video file in the background: yes

    - Use Low priorit CPU when completing partially transcoded video/audio files: yes

    Is there more options we can do to change the video resolution to max 720x405? Itīs becaus in High resolutions itīs very slow and i wanted smooth playback.

    I also tried to change the device profile (Sony Baravia KDL) and changed:

    - "MPEG_PS_PAL" dimensions to 720x405

    - "MPEG_TS_NTSC" dimensions to 720x405

    - Also tried to change the <videomax width="720" height="405" />

    - Jpeg and mp3 music settings work great.

    - I tried deleting the transcoding files after these modifications but it converts to a heavy format that has no smoothness and sound chops. So 720x405 was my idea to have a medium resolution but that played well.

    -the results from a file i transcoded were this:

    -And continues repeating this until the enf of transcoding.

    -It results in a 1280x720 and i wanted 720x405.

    -What am i doing wrong? I think the transcoder is not resizing videos.

    What can i do? Thanks.
