I have a Samsung HMX-F90 which records in MP4 format. No matter what I edit it in, Vegas, Pinnacle, Windows Movie Maker – they all see it as a 4:3 format. But if you call up the tags, this is what you find:
ID : 1
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Main@L4.0
Format settings, CABAC : Yes
Format settings, ReFrames : 1 frame
Format settings, GOP : M=1, N=15
Codec ID : avc1
Codec ID/Info : Advanced Video Coding
Duration : 47s 998ms
Bit rate : 8 286 Kbps
Width : 720 pixels
Height : 480 pixels
Display aspect ratio : 16:9
Original display aspect ratio : 3:2
Frame rate mode : Constant
Frame rate : 59.940 fps
The only program that PLAYS these files at the correct ratio is MPC-HC. Everything else plays in 4:3. In Pinnacle, right clicking the video brings up a box that has options: 16:9 4:3 with 4:3 selected, but both options are greyed out meaning I cannot change them. How in the world do I fix this?

In Vegas, if you go to the project properties, does it allow you to change it to 16:9?

720×480 is a 4:3 format, believe it or not, because the pixel aspect ratio is not 1:1, it's actually .9. That is to say, the individual pixels aren't square, they're rectangular. That's why DV is a 4:3 frame aspect ratio even though the pixels are 720×480, which is closer to 16:9.
If there's somewhere in your editing software to change the sequence pixel aspect ratio to 1:1, you should have your widescreen aspect ratio back.
