FLV, HD/lowres switch

Hi,

I just started using FLV-Embed, which is great. But I just received a couple of emails saying that viewers with slower machines couldn’t play my 720p videos. Is there another version, or mod to add a HD/SD switch the player. Similar to what vimeo has, clicking the button toggles between the highres and lowres files.

If anyone has any advice please let me know.

Thank you,

Eric
