Version 1.1.28vdr-1.1.28

- Using masks in EIT filtering to reduce the number of filters (thanks to Andreas
  Schultz).
- Fixed handling Ca descriptors (thanks to Stefan Huelswitt).
- Now only those Ca descriptors are sent to a CAM that are actually understood
  by that CAM.
- Re-enabled CAM communication during replay and on non-Ca channels. This requires
  a DVB driver with firmware version 2613 or later.
- It is now possible to do simultaneous recording and replay with a single DVB
  card, even with encrypted channels. This requires the use of the Link Layer
  firmware, version 2613 or higher; the -icam firmware is still limited to live
  encrypted channels only. Finally we have time shift for encrypted channels on
  single card systems!
- Enhanced detection of pending user I/O from CAMs to avoid sluggish reaction
  to remote control keypresses.
- Implemented "pause live video". You can now press "Menu/Yellow" or "Pause" on
  your remote control while watching live video to start an instant recording
  of the current programme and immediately start replaying that recording.
