OS: Windows 7 Professional SP1 64-bit (System is kept fully updated regarding Windows Updates, drivers, and software.)

NOTE: When I use the term "ratings" in the following paragraphs, I am referring to the "stars" that are displayed in Windows Media Player/Media Center and used for creating auto-playlists based on said ratings.

I use dBpoweramp CD Ripper to apply meta data, rate, apply DSP actions, and rip my CDs to FLAC. I then use dBpoweramp Bulk Converter to apply further DSP actions and convert my FLAC files to a separate directory as MP3s (I use the MP3s for streaming around my network and on portable devices while keeping my FLAC files as a reference "Music Archive," if you will). I have confirmed that all meta data is successfully transferred from the FLAC to MP3 version of the track - including ratings. dBpoweramp's Windows Explorer plugin displays the ratings perfectly, MediaMonkey displays the ratings perfectly, MP3Tag displays the ratings perfectly - but Windows Media Player/Media Center shows the tracks as "unrated." Is anyone else experiencing this issue or am I simply overlooking an important setting or switch in the dBpoweramp documentation?

Thanks in advance for any insights into this issue! Oh, just a note, I go to extreme pains in insuring that each song has complete and accurate meta data, therefore I do not allow ANY media application to alter that data. I even go so far as to set both my FLAC and MP3 files as "Read Only" once I have confirmed a successful ripping or conversion session using the appropriate dBpoweramp tool.
