I'm uploading some folders with pics and videos, when U1 finds a MPG it just remains uploading the file over and over again. It finish to upload and starts again. Any one have see this too? I'm seeing the queue with $ u1sdtool --current-transfers

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
If the MPG file is rather large (which I'm guessing it is), it sounds like you're getting corruption during the upload (not uncommon for large files).
Last I asked, Ubuntu One can't do incremental verification during an upload or download, so it can't verify the file integrity till the entire file has been uploaded. And when there was a problem, it has no way of knowing where the corruption occurred, so the only option is to try re-uploading the entire file.
You might try eliminating some avenues for network corruption, like if possible using a wired Ethernet connection rather than WiFi.
