intermittent flash compatability, please help

[Jim the Wideboy]

i've upload my nice new site www.trafficrecords.co.uk. the flash works when accessing the site on my nice new shiney lap top but doesn't seem to work on other machines. I've encoded flv's which are driven by embedded swf's in my html. I've used flash version8. Should i re publish/encode the swf's using a lower version of flash ie 6 or 7 so it is more likely to be compatable with peoples flash players.

Also I've experienced strange server dependent anomalies with my flash sub folders. On my old server when I encoded the flv into swf, I could get away with a simple path to my subfolders. ie
content path= "flash/flv"
However I switched servers from 123-reg to webfusion and the flash stopped working. I had to re-encode the swf's insode flash with a fuller file path to the flv's ie content path= "c:documents/trafficsite/flash/flv" then the swfs started working but only when accessed online with my lappy.
if someone could help me it would be amazing!
Thanks in advance.

I don't have much insight into the server thing (I usually stay away from hard-coded paths to FLVs), but the player stuff can be fixed pretty easily with basic player detection code. This code will prompt people who don't have flash 8 player to install it (a 900K download). Flash 8 video quality is much, much better than Flash 7, and Player 8 penetration is now at about 70-75%, so it would be a pity to make all those 8 users watch crappy Flash 7 video.
