samsung monte,cant get youtube/iplayer to work

[dave g]

just got a samsung monte touch phone.

its got all the bbc iplayer and youtube app/icons on etc,i connect to the net thru the wifi on it and can get the youtube pages up but it wont play any videos..same with bbc iplayer...yet with bbc iplayer i can download the video to the phone and watch in on the phone with the built in iplayer.

now is this because im connected using wifi?..i dont want to add a net package onto my tariff if they wont work

it says:
connected
video buffering.. 0% (this doesnt change)
then it says connection to the server has been lost

im not too phone savvy so no idea if its me etc
