That'll depend on how you are connecting. The best way of watching anything on YouTube through a BlackBerry is via Wi-Fi, it is the best way to get a stable and strong connection.
If you are connecting through a mobile phone network, the signal can vary in strength depending on how many people are connected to the same cell tower at the same time. Also, if you are trying to watch a YouTube video using a mobile phone signal, you will need a 3G connection. If you only have GPRS or EDGE you will suffer serious buffering problems while the handset tries to download the data.
Best advise? Use a Wi-Fi connection.
Hope that helps. If not, can you be more specific as to what you are experiencing and how you are connecting along with signal type and strength.
