You should have gotten a warning from eac3to, though, when extracting the THD track in the first place. It's not a good idea to extract THD tracks from seamless branching Blu-Rays. Audio and video will drift out of sync, because eac3to can't fix the audio overlaps with THD tracks, when demuxing them. You should convert to THD/WAVs directly from the original Blu-Ray structure. Then those "lossless check failed" warnings should go away and audio and video will stay in sync.

I thought eac3to will let you know if there is audio overlaps with THD tracks even if it can't fix the overlap or is it just a gap it warns you about? Even i did Spider-man 2 keeping the Truehd track and not converting to PCM because i thought there wasn't any overlap since eac3to didn't tell me there was. Can i just convert the truehd from the original blu-ray to pcm or just a WAV and not WAVs? Say if i convert to WAVs should eac3to tell me there was overlaps to fix?
