There are different possibilities of playing back media with the DVBViewer:
The open video command in the DVBViewer-menu lets you select a media-file for playback.
Drag & drop: Simply drag the video file with the mouse into the DVBViewer-window and let it drop.
If the DVBViewer is not running, just drop the video file on the DVBViewer-icon on your desktop.
Link the file-type (MPEG for example) with the DVBViewer. You can do this by right-clicking the file in the Windows explorer and selecting "open with" and "always".
Seamless playback: You can play back a media file, tune a channel and after that, you can continue watching your file at the break point by selecting last channel in the channel menu. By the way: All data are stored in the rec-database. That means, whenever you want to play-back a media-file you can choose to start at the beginning or the last position.
The DVBViewer Pro is based on DirectX and features a native demulitplexing filter. Thus all types of media can be played back, not only DVBViewer recordings. Because of DirectX you need to have the corresponding decoders installed, though.
To playback DVDs select DVD Playback in the DVB Viewer menu. With this menu you can also address the DVD's menu structure and select the desired chapter.
Sometimes you may have a DVD-structure on your harddisk as a VIDEO_TS directory. To watch such a "DVD" you must select Open Video in the DVB Viewer menu and then the Video_TS.ifo file. You can select different MPEG2 and audio decoders for playback with the GraphSelector Plugin.
Playback of ASF and ASX File Formats
The DVBViewer plays ASF and ASX files. ASF is a compressed file format that can store audio and video information and is designed to run over the Internet. ASF may also include slide shows and synchronising events. The big advantage of this file is that it is delivered continuously and starts playing almost without a delay. You don't need to wait for your audio and video files to fully download before starting to view them. For example, a 40 seconds-long AVI file can take more than 40 minutes to download over a 28.8Kbps modem. Because of this long download time, it would be impossible to deliver Internet-based training class that is 20 minutes long. When converted to ASF file, this class begins playing after just a few seconds. Practically, the file's size has no relevance to the problem.
You can open ASF files easily with the Open Video command in the DVBViewer menu.
ASX files are textual command files that manage streaming of ASF files. They are very small in size (about 1K) because they contain no data, just instructions. When a user clicks a link to an ASX file, the browser downloads it to the cache directory, launches the Windows Media Player, and then starts the streaming. The advantage of using ASX files over ASF files is their server location. ASF files can reside on different server types:
Windows Media Services Server. File names will start with mms://.
HTTP Server. File names will start with http://.
Local or network drive. File names will start with file://.
ASX files, on the other hand, are small text files that can always sit on an HTTP server. When the browser interprets the ASX file, it access the streaming media file that is specified inside the ASX file, from the proper HTTP, mms, or file server.
You can address such files via the Open URL command in the DVB Viewer menu. Just input or paste the URL and the file will be played back.
