unable to get video's from youtube

[itzick]

sorry for a lame question - but i could not find an answer for it
i am trying to get a channel "carambaworld" and "AdamThomasMoran"
i got URL's of


http://ComputerName:8083/user.rss?id=carambaworld&format=18&host=ComputerName&port=8083&size=25&orderby=published&removeDescription=true&removeTitle=false

http://ComputerName:8083/user.rss?id=AdamThomasMoran&format=18&host=ComputerName&port=8083&size=25&orderby=published&removeDescription=true&removeTitle=false

i do get a list of availible episods in iTunes - however i am unable
to download it
the error i got in iTunes is "there was a problem downloading XXXXX .
an internal server error occurred . please check that URL is correct
"

so it's seems to me that there is no problem with a server running ( i
do get a list ) .. but a java server unable to connect to outside to
get a stream ? .. some thing like this ..
where can i see for more logs/info / support ?
