LG VX-8100

i got the data cable and all the s/w on my computer. i am able to put music vids on the phone via bitpim, and by conveting them using mpeagable x4. the actual song plays the whole time, but the vid stops at 1 min 40 secs. i don't have a sd card yet, maybe thats the prob, but don't think so. also if any one had luck making the video play on the whole screen using mpeagable. i tried using image processing and setting the display dimensions 176 x 220, which i think is the size of the 8100 screen. any help appreciated
