FFMPEG creating WTV files that cannot seek

[ramitb]

Any WTV file I create with FFMPEG create WTV files but the seek function does not work with WMPlayer 12 or MCE Windows 7.

Commmand:

ffmpeg -i test.ts -vcodec copy -acodec copy test.wtv

i'm not attaching a file, you can use any test file you have.
