Like I said before, I have a newer Sprint 8830 and none of these settings have worked. These however kind of work:
1. 3gp (Sony Ericsson)
Use Directshow NOT checked
Options: H Quality
DVD language: Default
The problem I have now is that after watching about 10 min of video, the video will freeze and I have to restart the video and scroll to where I was. This seems like a nearly impossible thing to fix. My Included Desktop Media will not convert videos it just gives a "File cannot be transferred error".
Perhaps I will troubleshoot more, but I will check back if any Sprint Users find anything else out.
