probelms Rendering to wmv hd format

[Jaycexaveri]

Hiya
I wonder if anyone can help me.
I have ulead video studio 11 plus..
I am importing Hi def video from an Sd card in AVCHD FORMAT..
Editing is okay ,
Rendering to mpeg2 is okay...
But rendering to WMV HD just does not look right...
The end result is really low quality,, all pixeled...
Just doesn't look Hi def at all...
Is there anyway to make a good hi def movie for wmv hd without it looking bad..
Any help will be great
Thanks
Jayce
