- FusionHDTV
Made some progress on reading/writing the scheduling database that it uses.
Still need to work out how it calculates the channel number (8 bytes of data) and what the extra attributes are that it stores. But basic function appears to work.
Done it using ADO. Made a quick and dirty version to prove the principle and passed it over to someone in Australia to test.

- PostProcess
Had a request to suppress the "waiting in background" pop-up message box.
Easy enough to add - so done it. Implemented it in a more general way so that it could be easy to suppress all such boxes if needed. Ensured that it still writes to the log file though.

- Nebula DigiTV
Had a fault report saying that DABDig reported that it could not access the timer section of the Nebula DigiTV registry - but the scheduled recordings worked fine from the Nebula GUI. My guess is that the recordings (etc) are being stored in local memory of DigiTV and only flushed to the registry on exit. The installation is probably new ... and DigiTV has never being asked to exit while there were still recordings on queue. If that is right - then the easy solution for users is to schedule something in DigiTV and then exit from it (including the sleeping module).
Have now included code to create the "missing" key. The danger is that there really is something queued using and that my entry will overwrite it or not be detected.
Ideally .. Nebula should flush out their settings to the registry a bit more frequently - but that is an old request.
Build new version to create key anyway (251b06).

- General
Had a request to be able to pass the "StreamType" parameter to post-process.
Easy enough - 251b04

- Generic
Started to add in support for "generic" command-line interface.
Basically - looking at all of the currently supported command line driven applications and trying to see if I can make a generic one that could have handled any of them. Ultimately it should mean that users can add their won support for new tools more easily. Would handle basic things like stop/start tasks, send keys, use built-in timer both for waiting to start things and closing down at the end.

- Forum
First genuine query into the Forum - I guess found by following link from this Blog.
Shows up a couple of issues with the Forum message counter - but basically was fine.

- DreamVCR
Been in contact with author of DreamVCR (Windows scheduler into DreamBox). Started work on making the two work together. No command line options available yet so suggested a few.
In preparation for this - added new substitution commands for end date/time.
(251b03 built)

Had a request to be able to control ATi MMC from a remote PC (because recent DigiGuide seems to be using more CPU and making recordings stutter).
This sort of thing is more achievable with devices that support simply writing to a schedule file. In this case .. teh ATi schedule is held in the registry plus it might be necessary to stop/start tasks.
Remote control of the PC might be possible - but a relatively easy addition would be to make DABDig take a command line from a file (this is safer then pushing batch files over with the full command-line because someone could deliberately sabotage the system that way).
Including code to remain active and poll for a file is not great though because of the possibility of global variables not supporting being used twice (2nd run in loop).
Having an additional support task that listened on a port would be even better ... but would probably have to use a different programming language.
(251b02 includes ability to run using @filename)

- Multi-Device
Added code to allow to have mutiple device channel details within the [Default] section. Makes the map file smaller for users with something like video-capture card plus InfraRed control to set-top-box. Feedback from user - it works.

- General
Add link to new support forum in dabdig.ini

- TwinHan VisionDTV
Timing issue when closing tasks - if the task exits (for some other reason) between getting list of tasks and closing it down then it resulted in an uncaught exception.
Modified code to handle it.
In theory it could have happened where that I stop tasks but very small window and I think influenced by the fact that there are multiple tasks in VisionDTV and perhaps stopping one made another exit by itself later. Only reported once by one user. (250b11)

Started working on examining and implementing - but I think that it will not be very successful because they have a background task that is checking a Microsoft format database for scheduled entries.
Might be possible to write to it (perhaps using MDAC) but quite a bit of extra work.
However, the registry is used a bit so might be able to fool the main recording task into doing things.
Has support for TVPI/TVVI files - but cannot get it to read them in. I suspect that it only takes the encrypted ones that TitanTV generates nowadays.
Live viewing/channel switching will probably have to be via keystrokes unless I can get the TVVI working.

For HDTV users, need to add support for "Stream" that TitanTV can generate. Means extending the parameter set that already include PSIP-Major and PSIP-Minor.
