HDChina invite system is almost closed now, internal encodes are good but usually come after hdsky, mteam and hdarea when it comes to pre times.
Only dedicated seedbox are allowed now, using shared seedboxes won't even start the download and will lead to account being disabled.
All their 1080p and 720p encodes are set to free to leech for 12 hours after being uploaded.
HDChina is not considered a good or reliable bluray disks or remuxes source.
