I have an LG that errors on some Blu - not many though.
It probably has to do with the codec, probably not much you can do. There is some relation to how much the player costs, a better player typically has less of these issues. I have had my lg for 3 years and only had two disc errors.
From the vizio site--
Although all Blu-Ray players are tested to meet certain compliance guidelines all discs are created using a broad base of different formats. This can cause issues when trying to play certain discs.
Each movie studio has the ability to use a combination of different formats for audio and video that may cause the disc to be incompatible with the Blu-Ray player that you are trying to use.
This problem may not occur on every model or brand of Blu-Ray player. One manufacturer's Blu-Ray player may play a disc that yours may not and likewise your Blu-Ray player may play discs that others will not.
If you have a disk that is not playing in your Vizio Blu-ray player you can check the following items:
1) Check the Parental Control Level settings to ensure that the Parental Controls are not blocking the disk from being played. (Please refer to your Vizio user's manual for assistance in finding these settings.)
2) Make sure the disc is not badly scratched or smudged.
3) Ensure that you have the most recent firmware update available if your Blu-ray has firmware available.
Well... you get what you pay for. The machine was a bargin on sale at Target and worth every penny I paid and not a cent more. I'll buy a new player soon, a Sony at a moderate price. Then I can enjoy my Twilight Time films.
