Answer 1

He's already old. Supports few codecs. The only thing you can try is to explicitly set the DeviceType, maybe he can’t choose it by the file extension himself, but it’s unlikely to help. Recommend for example Windows Media Player to use. Windows Media Player in Delphi

Answer 2

Maybe there are not enough codecs.
