6700 Memory card problems!

[Littlebit4]

HI! I have been lurking for a while, and you guys seem to
know pretty much everything about these phones, so Please help!
I bought the 6700, then a Sandisk 2 gb card.
I switched the camera to memory card, but now
I can't find the pics I have taken. I think I have looked at every spot there is.
I went through doc, then, pics too, nothing.
Then, I tried to sync with windows media center to copy a cartoon for my son, and it states Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file.
So, then I used my Media Center and seemed to sync, but seems nothing is on my card still, except a few songs I put on it, right after I got it, and its a pain just to get them up.
Any help would be great!! I am very new to this phone.
Thanks guys!
