So I switched to doing research into how the codecs are matched to what a device can do. There are MTP format codes. I got the codes from <can't post url> for mpeg 4 (0x0000b982) and ogg (0x0000b902). Both the registry keys for ogg and m4a had not "FormatCode" DWORD value. <can't post url> I went to both locations, e.g. HKLM\SOFTWARE\Wow6432Node\Microsoft\Multimedia\WMP layer\Extensions\.ogg\, and added the appropriate FormatCode. I then reopened WMP and told it to sync the previously skipped file. Viola! It worked!
I only have one other post so I cannot post the URLs. Hopefully others that need the info can find it based on the description here.
