Thanks for the post and the links analyst99.
I will follow them up - but not tonight. I've done enough research for one day.
Each stock here on HotCopper seems to have it's die-hard defender. Well I'll say here and now that it isn't me for TVN - it has to stand on it's own merits. I want to be realistic and the more informed I am then all the better.
Sentiment is still a hold for me - have to keep in focus the meagre market cap.
