- DiSEqC support can now be generally enabled/disabled in the Setup menu. This
|
||||
may be necessary if your multiswitch gets irritated by the default DiSEqC
|
||||
codes '0' (thanks to Markus Lang).
|
||||
- Avoiding audio/video distortions in 'Transfer Mode'.
|
||||
- Fixed replaying in case there is no index file.
|
||||
- Fixed jumping to an editing mark when replay has been paused.
|

- Avoiding unnecessary code execution in the replay progress display (thanks

confirmation messages (like "Delete...") to "black on yellow".
|
||||
- Fixed display with DEBUG_OSD (it still crashes sometimes, esp. when replaying,
|
||||
but I can't seem to find what causes this... any ideas anybody?).
|
||||
- Avoiding audio/video distortions in 'Transfer Mode' by no longer actually
|
||||
tuning the primary interface (which can't receive this channel, anyway).
|
||||
Apparently the driver gets irritated when the channel is switched and a
|
||||
replay session is started immediately after that.
