How To - Check Your Tuners

What Channels are on each MUX : Channels and MUX - UKFree.TV
Example Method: To Test MUX1 : Use BBC1
Select BBC1 (LCN:1){MUX1-Tuner1} - Note Signal Info - S and Q (eg.MUX1-TU1=S66-Q100)
- Press REC Button
Select ITV1 (LCN:3) {MUX2-Tuner2}
- Press REC button
STOP BBC1 Recording, (press the STOP Button and choose the recording to stop)
Select FIVER (LCN:30) {MUX-COM4-Tuner1}
- Press REC button
STOP ITV1 Recording
Select BBC1 - {MUX1-Tuner2} - Note Signal Info - S and Q (eg.MUX1-TU2=S60-Q100)
- compare values with the first set.
To check another MUX simply replace BBC1{MUX1} with a channel from the new Test MUX.
(Swap over if already one of the MUX used to alternate the Tuners)
eg. Swap ITV1 and BBC1 in above method​
eg. To Test HD MUX replace BBC1 with BBC1-HD​
eg. MUX-COM4 - FIVER (LCN:30) is on the Test MUX so Swap FIVER and BBC1.
eg. MUX-COM5 - Replace BBC1 with DAVE (LCN:19) (or other COM5 Channel)

How To - Convert Video Files to DivX/XviD AVI Format for the Digital Stream

Many of you have a number of media files lurking on you computers and on cameras in various formats which you would like to play via the Digital Stream.
Some avi files play OK on the DS and others are not a recognised format or have no sound.
Since the June 2011 (4.12.r8569) update DSK have give the DHR8203U/DHR8205U/DHR8206U a Xvid/DivX media playback facility.
There is nothing in the v1.0 User Manual about video media playback as the manual pre dates the June update and has not been revised to cover this facility.
The following may help to explain why some .avi files play OK and some don't.
An .avi file is a multimedia container format within which the video and audio code is placed. The encoding of the video and audio data for placing in the .avi container is carried out by codecs which are normally (for home use purposes) part of a video converter programme.
It therefore follows that the type of encoding (codecs) used to create the .avi file must match the decoding capabilities of the equipment on which the file is the be played - in this case the Digital Stream.
It is also worth noting that many of the more popular codecs are 'lossy' which means that they reduce the quality of the video and/or audio in order to achieve compression and so reduce file size.
OK. That's the basic media encoding concept as I understand it so where do we go from here?
The update release notes state that we have Xvid/Divx media playback facilities so what's that?
Xvid is a video codec library following the MPEG4 standard. There are two DivX codecs, the MPEG4 DivX codec and the H.264/MPEG4 AVC DivX Plus HD codec.
From the User Manual v1.0 on page 55 we see that the Digital Stream understands the following codecs :-
1) Audio Codecs: MPEG1/Layer2,3, MPEG2, AAC, HE-AAC, Dolby Digital Plus
2) Video Codecs: MPEG2, MPEG4, H.264/AVC, VC-1
3) Additionally, we know from page 33 of the manual that the DS understands MP3 audio as it can play MP3 files.
 :::: It follows that if we use any of the above codecs to convert our media files they should play OK on the DS.
So what do we convert the files with?
There are a number of 'video converters' available for download but the one that I have had the most success with is Freemake Video Converter. It's freeware and it's available for download from here -
I won't list all of the file types that it can read or write as they are clearly set out on the web site, suffice to say that it has codecs that the DS can understand.
Also I won't go into great detail of how to use the programme as there is plenty of help for that too on the web site.
 ::: The conversion process is quite straight forward. Start the Freemake Video Converter programme and add the media file for conversion.
Select the 'to AVI' icon from the options along the bottom of the window. The 'AVI Output Parameters' window will now appear.
Click the downward pointing arrow to the right of the 'Preset' box and you will be presented with a choice of six conversion presets.
The Freemake programme shows the resolution of the original video file that is to be converted so when choosing a preset go for one that offers a resolution that is NO LESS than the original or there will be picture degradation.
Personally I would go for an increase in resolution as this seems to have no down side other than a nominal increase in recoding time.
 ::: I've not tried all the presets available but I've had excellent results from the HD 720p option. This preset up scaled and recoded a 1hr 05min long 640 x 360 resolution MPEG4 video to 1280 x 720 resolution on a few seconds over 5 minutes. I used the one pass encoding option and there was no discernable loss of picture quality compared with the original which was viewed on a computer monitor.
All that remains to be done is to define a place to save the converted file and decide if you want on or two pass encoding. Click 'Convert' and that's it.

How To - Prepare USB Stick For Software Updates

Although it should be possible to update with either a USB1.0 or USB2.0 stick, to stand greatest chance of having your USB stick correctly detected by the Linux OS that the DS uses then try and use a UBS2.0 certified stick. Some USB sticks may state they are USB2.0 but unless the original package had the following logo then they will not have been certified as fully compliant to the standards.
1. Plug USB stick in a Windows PC or Mac
2. Since USB sticks rarely come blank as the manufactuers normally load things like autorun scripts, backup software, password protection software etc on them, it is advised that you carry out a "Quick Format" to ensure the USB stick is truely blank before proceeding. When carrying out the "Quick Format" ensure the "FAT32" file system is selected.
NOTE - Carrying out the Quick Format is advised to minimise the possibility of any conflicts caused by something in existance on the USB stick, however you can attempt to use the USB as it is with other files (as long as they are not files for previous DS updates) and directories present if you wish after first of all verifying that the "File System" is "FAT32" in the "Properties" of the USB stick, if "File System" is either "FAT" or NTFS" then the stick must still be formatted. If you follow this route and a problem is encountered with the update then you can fallback on formatting the USB stick before proceeding with the following steps.
3. Ensure the update files downloaded from the website have been unzipped to your PC hard disk then copy the files across to the top level directory (root) of the USB stick.
4. To proceed with the update follow the relevent steps in FAQ#1, see

How To - Reduce Fan Noise

01. (Unofficial !) Slacken off the 4 screws holding the fan. Just loosen them slightly to de-locate the fan from the case and reduce case resonance. One 360° turn per screw then push the screws to position the fan away from the case back.
