Is there anyway to correct meta info including the art work if wrong or add manually?
Not in the current version, but something like this will be added down the road.
FYI - Media Player will use the embedded movie title (if present) over the actual file name. If you're getting incorrect results, you may check to ensure any embedded metadata in your files is correct.
would you please elaborate on how the metadata is fetched and what needs changed in the embedded metadata? For example, I have a movie named ‘Angels & Demons’ (in the embedded title) and the metadata fetched is for Charlie’s angels. Are special characters supported?
