I'm new to my Nokia 2700. I've added some personal movies files from PC to the phone for playback on the go. As the Nokia 2700 supported video format is limited, before transferring MKV, AVI, WMV, VOB files to my phone, I had to batch convert those files with Brorsoft's Video Converter. What made me satisfied, this video convert app brings me HD output video quality(least quality loss during the conversion), and it never fails.
