I just did the same for my cd collection a while ago, myself...your commandline is already correct for embedding the cuesheet. When you select Copy Image & Create Cuesheet/Compressed, it creates the cuesheet file first and then embeds it into the WavPack image file (it just doesn't delete the .cue file after, so it's left on your hard drive).
You can delete it manually afterwards, but I'd recommend hanging onto it...I had a couple instances of messing around with foobar where I accidentally deleted the CUESHEET tag in the image file, so I was able to use Windows notepad to just copy and paste the info from the .cue file back into the .wv file. You can also use fb2k to confirm that the cuesheet really is embedded in there, if you're not sure that the WavPack commandline in EAC is working properly.
You can also get rid of the
-w "Track=%n" and
-w "Title=%t" tags since you're ripping an image and not individual tracks, so they aren't necessary.
As for the highest compression, you can use -x1 switch in addition to -h, but it is
EXTREMELY slow, I remember reading here that it's only recommended to use one or the other, not both. The -x switch greatly slows down the encoding time but doesn't affect decoding time, whereas -h takes twice as long to encode and decode than if you used neither one (something to keep in mind when you want to transcode to a lossy format later). It's all in the user's manual here:
http://www.wavpack.com/wavpack_doc.htmlThe amount of space you'll save isn't a whole lot more IIRC and not worth the extra encoding time if you use both unless you're really squeezed for hard drive space. I stuck with -hm and am pretty satisfied with the compression.
As for the filename...yeah, that's a minor bug with EAC. You can just go ahead and rename it to filename.wv, and I'm willing to bet that's why your embedded cuesheets aren't being recognized in your media player.
I'm still new to this all, myself...so any mods/regs please correct me if I'm wrong (or feel free to add anything I missed).
