I'm french and I find them worthless because they almost have no HD stuff to show.
As for Global, it's a shame that they have been on the air for more than two years and have not yet begin to broadcast OTA. TVA and TQS shouldn't behave like them...
TVA and TQS are worthless, why bother. Instead of pressuring ExpressVu, you should ask them why they are not broadcasting OTA, especially TVA (which has seemingly no plan to broadcast OTA in the next year).
