<font face="Courier New, Courier, monospace"><br>
The Create BD Format contains 720 x 576/ 25i/p and 720 x 480/
29.97i/p<br>
<br>
Please verify if this these are SD 4:3 only? <br>
The wikipedia table lists only SD interlaced as valid SD BD-Video
format<br>
<br>
If so, SD 16:9 interlaced are missing, while SD progressive are
invalid?<br>
