# Known Issue: Capture Device Freeze with Multiple Instances (7.7.x)

Known Issue: Capture Device Freeze with Multiple Instances (7.7.x)

Affected Versions:

- WATCHOUT 7.7.0
- WATCHOUT 7.7.1

**Not affected:** WATCHOUT 7.6.3 and earlier.

 

*Symptom*

When you place **3 or more cues** referencing the **same capture device** (live input) on the **same display machine**, all instances of that feed freeze after 3-4 seconds. Reducing to 2 instances resolves the issue immediately.

- No error messages or warnings are displayed
- Affects all capture types: NDI, local capture cards (Magewell, Datapath), SDI input
- The issue is per-display-machine - using the same input on different machines is fine

Status **Confirmed and reproducible** by Dataton. The issue is on the bug fix list and will be resolved in a future update.

*Workaround*

- **Stay on WATCHOUT 7.6.3** for setups requiring 3+ instances of the same live input on one machine.
- Alternatively, limit to **2 instances maximum** per capture source per display machine.

###### Updates

This article will be updated when a fix is released.
