This plays correctly in mplayer2, which says:<br>
<br>
VIDEO: 720x480 29.970 fps 8900.0 kbps (1112.5 kB/s)<br>
Aspect ratio is 1.78:1 - scaling to correct movie aspect.<br>
VO: [xv] 720x480 => 853x480 Planar YV12 [fs]<br>
<br></blockquote></div><div>Right, but if you drop it in your video library and play it with myth, does it recognize the 'scaled dimensions' should be: 853x480 ? or does it display at the 720x480 resolution? </div>
<div class="im"><div>

That aspect should be 1.85:1 for 16:9, and 720x480 is actually D1 4:3 (or<br>
very close*), with the expected 0.9:1 pixel aspect; it only becomes a<br>
widescreen image aspect if you assume square pixels.<br>
<br></blockquote></div><div>I'm not sure what you are trying to tell me here. Are you saying that myth is doing the right thing and that I need to actually transcode the video to *force* square pixels to make myth display the video correctly? From what I have gathered the video stream is standard mpeg-2, NTSC which is 720x480, and the PAR is 32:27, which *should* yield a resultant display resolution of 853x480. </div>
