Wow. You must have some special, magical 811. Everyone elses has all or most the following problems with their 811's:
1. Dark image from SD outputs. (Some, including myself, also get a slight loss of detail in dark areas from one or more of the HD outputs, as well.)
2. Acquiring Satellite interuption when going from OTA channel to EPG.
3. Downloading EPG guide data way too often. (Always after an "acquiring signal", sometimes locking up or going into an endless loop of downloads.)
4. Intermittent closed captions.
5. Channel recall not working with OTA channels.
6. No OTA guide data. (A missing, necessary feature, as opposed to a bug.)
There's more. But, my old worn out brain cells can't recall them at this time.
