- Need of the Microsoft Framework.NET 3.5 (if not already install).
- Display analog and digital live video.
	* Analog tv or webcam device with WDM drivers.
	* Digital tv (DVB-T, DVB-S, DVB-C) device with BDA drivers.
- As fast as possible channel switching (This is the reason why I made this software).
- Still image capture (snapshot).
- Timeshifting (DVB only).
- Video recording (DVB only) in a ".dvr-ms" Microsoft proprietary file format
 (Because of the use of the DirectShow StreamBufferEngine).
	* Can be played with any DirectShow media player.
	* Information on Wikipedia
	* A tools to convert in mpeg2


- Launch the channel wizard.
- Select the parameters like the capture/tuner devices.
- Scan the channel over a frequency range.
- Double click on a channel and I hope for you it will work/

- 'SPACE' : snapshot
- '+' : Next numbered channel
- '-' : Previous numbered channel
- PAGE UP : Volume up
- PAGE DOWN : Volume down
- MOUSE WHEEL UP : Volume up
- MOUSE WHEEL DOWN : Volume down


- Some DVB drivers use 1 or 2 codecs.
	* With a 2 drivers model, fill the "Tuner Device" and the "Capture Device" channel settings.
	* With a 1 driver model, fill the "Tuner Device" and leave the "Capture Device" blank.
- Codecs
	* Video
		- MPEG2 Decoder Device="ffdshow Video Decoder" (
		- MPEG2 Decoder Device="Microsoft DTV-DVD Video Decoder" found in Windows 7.
		- H264 Decoder Device="ffdshow Video Decoder"
		- H264 Decoder Device="Microsoft DTV-DVD Video Decoder".
		- H264 Decoder Device="CyberLink H.264/AVC Decoder (PDVD7)" found in PowerDVD.
	* Audio
		- Audio Decoder Device="ffdshow Audio Decoder"
			but AC3Filter Lite ( must be installed for HD audio (AC3 or EAC3).

- Select several channels (with CONTROL and/or SHIFT keys) and select "Property" with
	the contextual menu to change the common properties (i.e.: If you want to change the
	video decoder device for several channels at once).
- Once a channel is tuned, you can tweak lot of codecs settings under the "Video/Filters" menu.
- To avoid synchronisation issue on TV out, just put the TV out as the main monitor. The
	synchronisation issue seems to appear on the secondary monitor. If it still not works,
	try the ReClock filter (
- For european, in order to avoid some jerky video you should put the monitor frequency to be
	a multiple of 25. For instance:
	* A PAL DVB video with 25 frames per second should be fluid on a LCD monitor set to 75 Hz.
	* A NTSC DVB video with 30 frames per second should be fluid on a LCD monitor set to 60 Hz.
- If an aspect ratio issue occurs, try another Mpeg2 codec (Mpeg2Dec, DScaler Mpeg2 decoder,
	Elecard Mpeg-2 decoder, ...), or try to adjust the ratio and save it to the channel.
- The GeForce 6600GT TV out seems a lot better than the ATI 9600.
- To read recorded .ts file you need the TSFileSource filter
- You can reorder the toolbar element with the mouse by maintaining the ALT key.
- Microsoft DirectShow upgrades
	* Windows XP TV tuner program stops responding or displays corrupted video
	* Some USB audio devices and some USB audio TV tuners do not work correctly together
		with a Windows Vista-based computer
