[Cisco FAQ] - On my D9850 I'm only getting audio, no video on some channels.

[Rajat Gupta]

Is this an hardware issue or configuration issue?

One possibility is that you tuned to a HD service or a MPEG 4 service. some broadcaster carry SD and HD services in their transport streams.

The D9850 only support MPEG 2 SD, if you require HD or MPEG 4 you will need a D9854 or D9858 receiver depending on your application.
