I'm not too familiar with FLAC, other than its lossless. I thought--without investigation--that there are some issues with the tags being standardized. I've also never used WMP or Meedio. The problems you may be having may be due to the nonstandard tags.
I highly recommend EAC as a ripper. In secure mode, there is nothing I'm aware of that will provide better rips. There are FLAC encoders that can be configured with EAC to generate FLAC rips instead of WAV or MP3. Takes a bit of time to get it set up, but once you do, it will automatically create a nice clean library as well--all my rips are stored automatically in /artist/album/trackno_song.m4a format. If audio is your principal concern, take the time to learn how to set up EAC. It really isn't that hard.
As far as playback, if you are committed to Meedio, your options appear somewhat limited. I just looked at their manual, and they don't claim to support FLAC as a format, just MP3, WMA, Ogg Vorbis, APE, and AIFF files. Of those, MP3 and Ogg Vorbis are lossy compression schemes. AIFF is like WAV in that it doesn't support tags except under some kludgy nonstandard implementation. That leaves you with APE or WMA. APE (Monkey's Audio) is supposed to be good, but I don't think the decoders are broadly available other than on a PC platform. As an archival format, it leaves me nervous. WMA will ultimately succeed just because its MSoft. But, you have to make sure that you specify lossless encoding rather than lossy encoding since it will do both.
I noticed there is a Meedio foobar2000 plugin. If you are committed to Meedio, you might think about that, since foobar is a well respected player. The note on the plug in says something about mp3 playback, but foobar does FLAC natively.
Good luck.
