Description
Hi,
my backend just refused to start a recording with this message:
2005-08-29 22:08:40.315 AutoExpire?: Found 1 recorders w/max rate of 138 MiB/min
2005-08-29 22:08:40.316 AutoExpire?: space: 2.0 GB w/freq: 10 min
2005-08-29 22:08:42.303 Reschedule requested for id -1.
2005-08-29 22:08:43.005 Scheduled 1 items in 0.7 = 0.67 match + 0.04 place
2005-08-29 22:08:43.009 Recording starts soon, AUTO-Startup assumed
2005-08-29 22:08:43.011 Estimated program length: 150 minutes, size: 26017 MB, free space: 14484 MB
2005-08-29 22:08:43.011 SUPPRESSED recording 'Eyes Wide Shut' on channel 1008 on cardid 1, sourceid 1. Only 14484 Megs of disk space available.
What's wrong here? This is an ordinary DVB-T budget card (WinTV Nova-T) and the channel should not have more than 5 MBit/s.

AutoExpire? is disabled.
What happens if I enable AutoExpire?? The record won't be suppressed but no other recordings will be deleted? Or will it delete recordings until 26 GB are free?

In your case, it will free space until there are 2GB free every ten minutes.

You need to enable AutoExpire?.
The file size prediction is working as intended for HDTV capable sources.
19400000 /* bits per second */ / 8 /* bits in byte */ * 60 /* seconds in minute */ * 150 /* minutes in recording */ * 1.25 /* 25% safety */ = 25 GB
Recordings shouldn't be suppressed because of this unless AutoExpire? is disabled. There is no way for MythTV to know the channel transmits at just 5000000 bps. You are welcome to improve GetMaxBitrate?() to take previous recordings on the channel into account.
