Why has the TV or other device connected to my CableCARD suddenly lost access to certain FiOS channels? Why has the TV or other device connected to my CableCARD suddenly lost access to certain FiOS channels? To continue to enhance and maintain the FiOS TV network, Verizon occasionally launches a maintenance release or network upgrade which could impact your access to certain channels via a CableCARD connected device.
If you use an MPEG4 compatible TiVo® DVR or other device to access FiOS TV, you should not be impacted. If you experience channel access issues with a CableCARD connected device, you should first ensure that your device is MPEG4 compatible before contacting Verizon.
Please check with your device manufacturer to confirm compatibility with MPEG4 digital video delivery.
