Default MPEG Viewer problem please help

OK I wanted to know if I was doing anything wrong with it I plugged my Sansa e260 into my PC in MSC mode and downloaded a video as an mpeg file and placed it on my sansa (in a new folder) then I unplugged it safely and waited for it to reboot and I went to watch my video and it was going really fast and sounded like a chipmunk I tried this on 3 different videos all with the same result so am I doing something wrong?

Did you just downloaded the file from the inernet, or you encoded it by yourself? If you encoded it, which program did you use?

Sounds like Rockbox doesn't like the way the video was encoded (wrong options on it). I've noticed on my computer a few times where I'd convert a 15 second clip only to find it'd be 3 seconds after it finished, playing 5x fast.

I Downloaded the video from Youtube with Save2PC and saved it as an mpeg file and I used the daily build of rockbox on my sansa which had the mpeg viewer already in it

Yeah. You need to convert it so that the output file is....
video bitrate: about 200kbps runs smoothly most of the time
video codec: MPEG2 or mp2 is fine but mpeg1/mp1/mpeg works
audio codec: MP3 at about 192kbps works fine
audio channels: 2 (stereo)
audio sample rate: 44100 Hz
resolution: the sansa screen is 220x176 and Rockbox automatically rotates videos so get it as close to this as you can without distorting the aspect ratio too much, but never go over the LCD resolution

also you should make sure that the MPEG player plugin isn't configured to play at maximum FPS, this could explain the 3-5x speed.

I use mediacoder http://mediacoder.sourceforge.net/download.htm. It seems to work fine for all of my conversions, but there are other methods on the MPEG player's twiki page (http://www.rockbox.org/twiki/bin/vie...uginMpegplayer).
That should clear things up.

Another thing, depending on the age of your build, a wrong sample rate for the audio could result in a file that plays way too fast.
