For good replay in Transfer Mode on full featured DVB cards you may want to apply
the patch from ftp://ftp.cadsoft.de/vdr/Developer/av7110_v4ldvb_api5_audiobuf_test_1.diff
to the driver (thanks to Oliver Endriss).
+
+2009-01-06: Version 1.7.3
+
+- Updated the Russian OSD texts (thanks to Oleg Roitburd).
+- Fixed handling the 'pointer field' in generating and parsing PAT/PMT (thanks to
+ Frank Schmirler).
+- Fixed handling modulation types for DVB-S transponders when processing the NIT.
+- Changed cDvbDevice::GrabImage() to use V4L2 (thanks to Marco Schlüßler).
+- Added a poll to cDvbDevice::PlayVideo() and cDvbDevice::PlayAudio() to avoid
+ excessive CPU load (this is just a makeshift solution until the FF DVB cards
+ can play TS directly).
+- The recording format is now Transport Stream. Existing recordings in PES format
+ can still be replayed and edited, but new recordings are done in TS.
+ All code for recording in PES has been removed.
+ The following changes were made to switch to TS recording format:
+ + The index file format has been changed to support file sizes of up to 1TB
+ (previously 2GB), and up to 65535 separate files per recording (previously
+ 255).
+ + The recording file names are now of the form 00001.ts (previously 001.vdr).
+ + The frame rate is now detected by looking at two subsequent PTS values.
+ The "frame duration" (in multiples of 1/90000) is stored in the info.vdr
+ file using the new tag F (thanks to Artur Skawina for helping to get the
+ IndexToHMSF() calculation right).
+ + Several functions now have an additional parameter FramesPerSecond.
+ + Several functions now have an additional parameter IsPesRecording.
+ + The functionality of cFileWriter was moved into cRecorder, and cRemux is
+ now obsolete. This also avoids one level of data copying while recording.
+ + cRemux, cRingBufferLinearPes, cTS2PES and all c*Repacker classes have been
+ removed.
+ + A PAT/PMT is inserted before every independent frame, so that no extra
+ measures need to be taken when editing a recording.
+ + The directory name for a recording has been changed from
+ YYYY-MM-DD-hh[.:]mm.pr.lt.rec (pr=priority, lt=lifetime) to
+ YYYY-MM-DD-hh.mm.ch-ri.rec (ch=channel, ri=resumeId).
+ Priority and Lifetime are now stored in the info.vdr file with the new
+ tags P and L (if no such file exists, the maximum values are assumed by
+ default, which avoids inadvertently deleting a recording if disk space
+ is low). No longer storing Priority and Lifetime in the directory name
+ avoids starting a new recording if one of these is changed in the timer
+ and the recording is re-started for some reason.
+ Instead of Priority and Lifetime, the directory name now contains the
+ channel number from which the recording was made, and the "resume id" of
+ this instance of VDR. This avoids problems if several VDR instances record
+ the same show on different channels, or even on the same channel.
+ The '-' between channel number and resumeId prevents older versions of
+ VDR from "seeing" these recordings, which makes sure they won't even try
+ to replay them, or remove them in case the disk runs full.
+ + The semantics of PlayTs*() have been changed. These functions are now
+ required to return the given Length (which is TS_SIZE) if they have
+ processed the TS packet.
+ + The files "index", "info", "marks" and "resume" within a TS recording
+ directory are now created without the ".vdr" extension.
+ + The "resume" file is no longer a binary file, but contains tagged lines
+ to be able to store additional information, like the selected audio or
+ subtitle track.
+ + cDevice::StillPicture() will now be called with either TS or PES data.
+ + cDvbPlayer::Goto() no longer appends a "sequence end code" to the data.
+ If the output device needs this, it has to take care of it by itself.
+- Fixed cPatPmtParser::ParsePmt() to reset vpid and vtype when switching from
+ a video to an audio channel (thanks to Reinhard Nissl).
+- cDvbDevice now uses the FE_CAN_2G_MODULATION flag to determine whether a device
+ can handle DVB-S2. The #define is still there to allow people with older drivers
+ who don't need DVB-S2 to use this version without pathcing.
