Tvheadend

Recently moved to 4.3 latest branch after using 4.2 for many years. I use the "Use EPG running state" turned on for DVR recordings. Recording TV in the UK over DVB-T.

I have 30 seconds extra warming up time and 5 mins pre-recording padding configured in the DVR profile.

I've noticed that sometimes TVH will commence recording to file for a short period of time (5 - 10 secs) and then the status would change from "Running" back to "Waiting for EPG running flag". Then later when the EPG running flag is detected TVH starts recording but to a new filename.

States seem to go:

- Scheduled for recording
- Running (with filename: /recordings/Channel 4 HD/2021-12-13-18-00-The Simpsons.ts)
- Waiting for EPG running flag (with filename: /recordings/Channel 4 HD/2021-12-13-18-00-The Simpsons.ts)
- Running (with filename: /recordings/Channel 4 HD/2021-12-13-18-00-The Simpsons-1.ts)
- Completed OK (with filename: /recordings/Channel 4 HD/2021-12-13-18-00-The Simpsons-1.ts)

Note the different filenames for the last two states.

After the recording is completed and looking at the filesystem the two files are sized:

2021-12-13-18-00-The Simpsons.ts - 5,730,804 bytes
2021-12-13-18-00-The Simpsons-1.ts - 767,236,648 bytes

This is unexpected behaviour and different to TVH 4.2 (latest) where it would go straight from "Scheduled for recording" to "Waiting for EPG running flag".

Is this a bug or expected?
