hi .. im not 100% sure but my iriver mp3 player (just bought) mentions this & refers to the SAMPLE rate. so it may be an idea to recheck the settings of both your original file & the device u are playing back on. If its not compatible with your playback machine u may have to re conf it .. good luck .. russ
PS .. im not sure if its AVI or DVD u refer to ..
.. but a program i use called Virtual Dub is good for editing & ive burnt quite a lot of pop videos (albeit SVCD) using my capture card & then cleaning them up in VirtD. It wont handle all files but quite a lot.Their homepage has lots of links to freeware video stuff. worth a look.
