BSR, download the latest MusicLobby as there recently have been some fixes put into place to make the MuLobby / MediaCenter integration go smoother:
ADDED: Autoconvert Images within J River Media Center to be MusicLobby JPG format compatible (Save's file to same directory as original image in Non-progressive JPG)
Supports converting progressive jpg, bmp, dib, rle, wbmp, gif, ico, jpeg, pcd, emf, wmf, png, tga, targa, tif, tiff, and pcx
Note: Images still must not be embedded within the tag
Also, there is a DVDLobby recent update with some fixes.
And, make sure you are on MainLobby 2.75b as there were some neat updates and fixes there too (I think you are already on this one).
