So HiDownload 7.99 downloaded a 1.16 GB file. It has the same video resolution of 680x382, the same 15fps, the same AAC audio. I can't play it in both Applian FLV Player and KMPlayer without fixing . And I don't see any increase in quality.

The only difference I can see is that the video downloaded by Replay Media Catcher is 22 min 07 sec long, while the video downloaded by HiDownload is 25 min 23 sec long.
