Question about Vizio VX37L Television
90% of the time it will scan through the Anaalog channels and freeze about 3/4 through digital cahnnels. Usually freezes after 7 digital channels, but sometimes 30. On rare occasion it completes the scan.

SOURCE: Digital channels freeze
I also had this channel 5-1 freezing problem and spoke with Vizio support a few times. They thought the problem was the SSID code from the local CBS station and said they would try talking with them. I am not certain if they did this or not, but, as of mid December, my Vizio no longer has this problem.

Do you remember in the old days when you got bad reception and the TV would get snowy? That was due to the signal strength of the incoming signal was not strong enough. We with digital TV you can still have a situation where the signal is weak, since you are looking at a digital picture the video and audio are packetize, and being packets they are first fed into a buffer and then sent to the decoding section of your TV. Now think about this when the signal becomes weak and the data stream is corrupted to the point that the processor rejects the stream that data which is in the buffer plays out and the last thing in the buffer is what you see on the screen (frozen image on the screen) until the signal strength goes back to normal and the buffer fills up again.
How do you stop this, well that's a hard question since the buffer underflow is the result of signal degradation, the cure would be to prevent the signal from degrading. This can be done with the use of an HDTV antenna (too expensive), an amplified antenna (priced ok for some but still too pricy for most), a rabbit ear type antenna with an amplifier added (this will work for most people), or just a plain set of rabbit ears (dipole antenna). All of these are options that can help you.
I hope this helps
