vrecord exited a form in an unexpected way (P1_ERR=234)

I'm getting this error after installing latest Vrecord update. Crashes immediately after hitting enter to start recording.
All appears to be fine in passthrough mode.

I've tried a clean install but same results.

Here's the info from terminal. Thanks! Nigel

```
Hit enter to start recording

Could not find disk: /dev/
Close the playback window to stop recording.
