BitRate View also reports the file as 352 x 288 so I guess Media Player is wrong.
Both BitRate View & Virtual Dub list another video I was trying 2 burn as 352 x 288 @ 25fps which is the PAL VCD standard but Nero says the file is incompatible & needs 2 B reencoded.
Anyway the fact that I can detect the correct frame rate will let me decide if a file is best made as a PAL or NTSC VCD.
celtic_druid, I am as confused as ever now that I know a file has 2 ways 2 measure it's resolution but thanx anyway!!!
