Okay everyone I love taking videos with my 720p camcorter and I would like you use linux editing my videos because kdenlives is a awesome program except for one small thing is its playback. I am trying to edit a video where people are talking and the video and audio playback in kdenlive is sluggish and laggy and the audio is all weird and buggy I found a playback option under kdenlive prerences i tried every audio codec thing and its all the same what my problem please someone help me out here please please please!!!!!!!!!

Could you specify :
- your version of Kdenlive (if not 0.7.7 please upgrade)
- your OS
- your hardware (processor, ram memory etc.)
- video format or at least camcorder model

720p camcorders quite often record in mpeg4, and Kdenlive on a decent computer (I would say roughly at least 2Ghz processor and 1GB of ram) has not problem with playback.
