Mochi Theme (SMP) - Minor Revision Possible?

I have the WD TV Live SMP, most recent generation. I’d like to make one simple change to the Mochi theme. I do not like the movie backdrops when viewing in gallery mode because it makes the information text difficult to read. It’s my understanding that a simple change to one of the XML files can remove the backdrops. I would be happy with a simple black screen instead of the backdrops. 1) Can this be done? 2) If so, how do I find the XML file that needs to be edited, and how do I apply the change? Thanks for your help.

Open  rv_gallery_browse_page.xml   …

Replace this

<?xml version="1.0" encoding="utf-8"?> <image image="image/keyboard_mask_bg.png" x="0" y="0" w="1280" h="720" bg="1" disable="@@disable-thumbnail-bg" /> <image image="@@preview_rect_image" default_image="@@default_preview_rect_image" x="0" y="0" w="1280" h="720" textcolor="@@preview_rect_color" keycolor="1" ignore_keycolor="1" bg="1" /> <image image="image/Gallery/video_browse_gallery_overlay.png" x="0" y="0" w="1280" h="720" bg="1" /> <ctrlgrp>

With This

<?xml version=“1.0” encoding=“utf-8”?>
<page background="./image/RV-BG.jpg">
<image image="image/video_option_bg.png " x=“0” y=“0” w=“1280” h=“720” bg=“1” />

Thank you, but where do I find that file? I have the SMP (not the hub). I searched this forum and saw that I need to downolad the GPL code, which I did. But after extracting all the files I could not find the Mochi theme XML files anywhere within the download.

Legacy Theme for SMP:  contains  rv_gallery_browse_page.xml (Which Mochi Theme also uses. They are the Same File… “Legacy Theme”  is mostly just different color graphics)
