Topic: DISH DVR Settings and troubleshooting for closed-caption/audio sync
Most DISH receivers work fine with TVG. We have discovered that some DISH DVRs require a setting change in the DISH menu to sync the CC and audio, and other DISH DVRs have a software bug that causes the closed-captions to lag behind and/or have garbage characters. Since TVG depends on the closed-captions, this DISH bug causes problems for TVG.
The good news is we've found some possible solutions for you to try with DISH.
If you're having an issue with DISH, please try the applicable steps below, then email us at firstname.lastname@example.org and let us know: 1) which DISH DVR model you have, 2) which of the steps below you've tried, and 3) if the steps below worked to correct the issue for you, or not.
DISH MODEL ViP 622, maybe others: TV1 Audio Sync: The receiver can be set to synchronize the TV1 audio to the SD video outputs.
Go to the TV1 Audio Sync menu by pressing MENU on the remote, selecting System Setup (6), Installation (1), then TV1 Audio Sync (7).
Select Standard Definition, then select Done.
DISH MODEL ViP 722k, maybe others: There is a DISH closed-captions bug that only seems to occur with some dual tuner DVRs that support two TVs on one receiver. Changing the DISH Mode to the 2-TV setting seems to make it less likely for the bug to surface that causes the closed-captions to lag behind and/or create garbage characters.
Follow these instructions to change the setting:
1. Reset the DVR (the button may be under a panel on the front of the DISH DVR). Either press the reset button, or hold in the Power button for ten seconds, until the receiver starts to reboot. You should see the DISH logo on your TV.
2. Once you see normal TV again, press the Mode button on the front panel of the DISH DVR and change the setting to 2-TV mode: There are three sets of lights on the front panel; Mode, TV1 and TV2. 1-TV Mode has 1 square, 2-TV Mode has 2 overlapping squares. The TV2 light will light up in a blue color, too.
3. The cc/audio out of sync bug may still surface, however, this setting should give you many hours of profanity-free viewing. If the cc/audio timing gets off again, you need to repeat the reset step in #1.
In this setting, you will lose the picture-in-picture ability, however, it fixes the CC problem and TVG will work properly. If you're watching sports, and want PIP back to watch two games at once, you can simply change the Mode back to the 1-TV mode again. Then change it back later for TV shows and movies.
