Lastly, "51h264" would be the audio specifications. "5.1h264" would be correct for a 5.1 surround sound encoded in H.264. So they're looking for a digital copy of the movie in Hindi, 1080p resolution, probably a DVD rip or web source with 5.1 surround sound using H.264 encoding.
First, "paheli2005" might refer to a Bollywood movie. "Paheli" (2005) is a film directed by Kabir Khan, starring Shah Rukh Khan and Twinkle Khanna. So the user is likely looking for that movie. The "hindi" part specifies the language, which makes sense as the movie is in Hindi.
