That's a different but interesting issue wordpressvoxbox13! :-)
There is a combination of 3 reasons that result in this behavior:
- on the homepage your theme is very likely using "the_excerpt" to fetch the teaser content
- the_excerpt is treated by wp youtube lyte (so your httpv-links are processed and turned into an empty div with the noscript-text)
- as there is no other text in the post, the only text in the post, the noscript-one is shown
To solve this, you could make sure to add text before the lyte-embedded video. Given the length of the_excerpt (55 words by default), you'll quickly loose the noscript-text.
On my side I just might tweak the code a bit to remove the noscript-tag if the content parsed is an excerpt, that improvement might land in the next version.
