TEST REPORT PVR Software

Recording TV Programs via UPnPThomas Haring

Recently, in the 11-12/2014 issue of TELE-audiovision, we introduced the DVR Studio HD 3 software package. This innovative program makes it pos-sible for a user to create a DVD or Blu-Ray disk from a previously recorded program on a digital receiver with just a few mouse clicks. So the question is what‘s the easiest way to get these recorded programs from the receiver onto your PC?

There are three ways to do this. The first way would be to connect the re-ceiver‘s storage device directly to the PC. But this only works with external storage devices and as long as the ex-ternal device is connected to a PC, the receiver can‘t record any other pro-grams.

Another way with most PVR receiv-ers is to transfer the recording to the

PC through an Ethernet connection or via WiFi. For some manufacturers DVR Studio HD 3 offers this ability directly through the software.

The third method, namely the trans-fer of recordings via UPnP is not only a new feature in DVR Studio HD 3, it is also very easy and comfortable to use and, above all, works with all UPnP compatible receivers. It is also the fast-est method.

We‘ve already reported quite often on UPnP (Universal Plug and Play) in the course of a number of different TELE-audiovision receiver tests. This stand-ard is used for backup control of de-vices within an IP based network and has proven itself very advantageous in the audio/video world. The days of pro-prietary transmission methods are long gone; through UPnP every compatible

ent sized recordings and managed to achieve the same results every time. We also appreciated the fact that the transfer via UPnP was exceptionally stable and never crashed during our tests.

DVR Studio HD 3 also never com-plained at all while working with our network hard drive. We were able to transfer transponder stream files easily and effortlessly via UPnP to our PC for further processing. In this case though, there didn‘t seem to be any noticeable speed advantage during the transfer. A 4 GB recording needed about 2 min 30

sec to transfer from the network hard drive to the PC and it didn‘t matter if it was through Windows Explorer or through DVR Studio HD 3.

In the course of our tests we discov-ered a little problem with the satellite receiver/DVR Studio HD 3 combination: if a FAT32 formatted storage device is used and if the desired recording is made up of multiple files (with FAT32 storage devices the files are divided into 1 GB partial files), DVR Studio HD 3 will transfer the first available file and then ignore all the rest. The cause can be found in the firmware of the receiv-

er. The solution is very simple: instead of using the old-style FAT32 file system on the hard drive, the NTFS file system should be used. In this case the files are not split up and all of the problems associated with the splitting up of files is now a thing of the past.

DVR Studio HD 3 shows us how you can transfer TV recordings from any network device very quickly and pro-cess it further using the software. This makes the creation of DVD and Blu-Ray disks all the more easier and enjoyable.

receiver can communicate effortlessly with every available PC, media center and even other receivers within a net-work. We were thrilled to see that Haen-lein Software recognized that more and more manufacturers were integrating UPnP in their receivers and immediately reacted by adding this standard to their latest version of DVR Studio HD 3.

In order to test the UPnP transfer ca-pabilities we used the DVR Studio HD 3 software in combination with a Techni-sat Digit ISIO S satellite receiver and a Western Digital network hard drive. Both of these devices were hard-wired into our local network through a router onto which our test PC with Windows 8.1 was also connected.

First we tested the new function in conjunction with the satellite receiver and setup a new project with DVR Stu-dio HD 3. In the dialogue field where the desired recordings are added you‘ll see a list of the local files as well as the selection UPnP. All you have to do is click on the UPnP selection and the software begins to scan the entire local network in just a few seconds for any usable UPnP sources.

In our case both the satellite receiv-er and the hard drive were recognized without any problems and the availa-ble multimedia data and recordings on both of these devices were now acces-sible. The user simply has to highlight one or more of the recordings or files and then click on the „Transfer Record-ings to PC“ button to begin transferring the selected items to the PC. We liked that DVR Studio HD 3 showed the size of the selected files so that the user can get an idea of how much time would be needed for the transfer. Since we men-tioned „time“, we were pleased to see that the transfer from satellite receiver to UPnP was much faster compared to the original software from the receiv-er manufacturer. We had to perform a comparison test; we simply couldn‘t resist. The exact same recording with a size of around 4 GB took about nine minutes via UPnP to load onto the PC whereas the original software needed 19 minutes for the same task; 10 min-utes longer than via UPnP. To make sure that this speed advantage really existed we repeatedly performed this measurement with a number of differ-
