@ -350,10 +350,12 @@ Video Disk Recorder Revision History
- Encrypted channels can now be selected even without knowing the PNR (however, it
is still necessary for the EPG info).
2001-01-20: Version 0.71
2001-01-27: Version 0.71
- Fixed 'Transfer Mode' in cases where a non-primary interface was switched to
a channel that only the primary interface can receive (which could happen in
the EPG scanner).
- The EPG scanner now starts with the first channel (it used to start with the
second channel).
- Reacitvated setting the PNR.
- Adapted the frame scanning to the new muxing of the driver.
