Is there any plugin that can grab the related youtube videos automatically to a page, based on the keyword I provided? Please advise, thank you.
Yea. There is a Plugin ! There are two versions. One is the Premium and the Other is Free. THe Free Version only Supports Youtube and one adult site. I advise you to buy the Premium Version. I bought it for 20$ Unlimited use License. Its Amazing. Adding feeds is also Quicker.
I can confirm that I use this plugin (paid version) on a shared hosting plan on GoDaddy.com. You can check out the site here: http://www.mmastreamed.com It is a little bit of an investment to get it up and running (the theme also cost money), but it is well worth it. Just working on monetizing the site now. The only knock I have against this is that JOTA (the creator of the plugin) hasn't been online for about a week on his forums and I have a question that I am looking to get answered.
Try wp robot.i think this is the best for auto posting of youtube video based on particular keywords.
Glad Tubepress seems to be a hit. And remember, Wordpress can also embed URL's directly from YouTube and several other similar sites. No special embedding code needed. Just drop in the URL from your browser -- with the editor set to HTML. And/or embed using one of the little media icons above the entry screen and/or use a plugin and/or use the embedding function of the TinyMCE editing plugin. I've stopped using plugins to embed videos from YouTube. They just add code and slow down the site. But I do like and use the FV Flowplayer plugin for FLV, MP4 and MOV videos. Hope this helps --
