Record with timecode as source but false on start at Timecode causes crash

1. Add skeletal mesh to take recorder
2. Add a valid timecode source using a media profile
3. Set recording clock source to "Timecode"
4. Set "Start at Current Timecode" to false
5. Start recording

Engine will hang for a number of minutes or crash

If the editor doesn't crash recording will start but then saving will either take a number of minutes or crash (depending how far from zero the current timecode is)
