Final Straw - Back to slow buffering/searching/skipping on youtube html playlists

Hi

My jwplayer is setup as a wordpress plugin with xml playlist here: www.diwireless.com.au.

After months of having major buffering/hanging issues when trying to use the searchbar to skip to different points of my mp4 files (small 3min and large 35min) I finally decided to link to youtube urls in my xml playlist and this made searching/skipping to points as good as it is on youtube. Fantastic.

Then the issue arose re youtube support in jwplayer (http://www.longtailvideo.com/support/blog/17773/a-word-about-youtube-support-in-the-jw-player). Fine - eventually got it working again with the temp fix Longtail provided. Working just like it was before. Thanks.

Now for some unknown reason I am BACK TO SQUARE ONE with horrible hanging/slow searching when using the searchbar to skip to points of the media - particularly long (35min) files but even on small 3min ones.

What happened? What changed this time? Has anyone else experienced this?

To be honest, as a person who is obviously not a developer, and self taught in building my site - I have struggled SO much with trying to get the JWplayer to perform the way it is promoted/seen elsewhere that this evening I started looking at other media player options - and will be making the switch if I can't get this fixed one (hopefully) last time.

I hope someone can please help on this thread. Many thanks.
