I downloaded and tested EAC (I normally use dbpoweramp as it gives a lot more tagging help) on a number of cds, ripping to WAV. All of them had track lengths in the metadata and all had track lengths when brought into OCD using Media Scan of the WAV files. I am using Windows 7. I don't have any other suggestions; the only time I have not had track lengths is some Adds from Discogs and almost all Adds from Amazon (I add as soon as I have purchased and album and then revise when it arrives).
