DRM Converter - Tunebite FAQ

When converting large videos, a very high performance of your PC is required. If your PC isn't fast enough, such frame drops can occur.

You can reduce the resolution of your videos in the following way: Go to 'Options> Video> Video size' and select 'Optimized for mobile devices'. Then try to convert them again. You should experience no frame drops anymore.

Another reason for frame drops can be running apllications in the background. Please close all other applications, and try the conversion with Tunebite again.

Tunebite might be using the original soundcard instead of the installed driver. In the Control Panel select manually the audio driver 'Tunebite High-Speed Dubbing' as default device for sound playback.

Please try with muted sound output during recording. Please don't use your PC during recording and switch of normalization in the option. If this doesn't help please try with lower speed and with less recording slots.

The main purpose of Tunebite is the digital copying (high speed dubbing). For this, the correct detection of the soundcard is not neccessary.

Only for the analog mode, the detection is neccessary. The sound test has to complete succesfuly. You can try to select your soundcard manually, is the automatic detection doesn't work.

This message points to the fact that the connection to the server was interrupted during the download of the setup-files. To eliminate the problem, delete the Cache of your browser, open your browser again and download the setup-files.

Windows Vista unfortunately limits the recording speed per slot to 1x. A faster conversion would result in recording errors.

However, Windows XP allows recording of WMA files with 3x speed. Using 4 slots this results in a total speed of 12x. You can force the utilization of 4 slots in the options. But please keep in mind that your PC has to be powerful enough to use such high speeds. If you experience recording errors, you should lower the speed and/or the number of slots.

Under certain circumstances, especially after a conversion error or if you plugged-in and removed a USB sound device, it is possible that Tunebite sets the wrong system default playback device.

Please check under Start Menu -> Control Panel -> Sound -> Playback device, which device is set. This must not be "Tunebite high speed dubbing". Choose your normal sound card/or any other plaback device you want as standard. 

It can happen that a "playback error" occurs when trying to convert files with Tunebite. In this case please play that file once with the original application. That's Windows media player for WMA/WMV files, and iTunes for m4v, m4p, .aa files and similar.

If you do that, the player will try to acquire the license needed to play that file - and might ask you some questions (e.g. if you want to update the software, assign the player as default to some media types, or similar questions). If dialogs asking such questions occur, please make sure they won't appear again next time.

Afterwards Tunebite should be able to perfectly convert those files.

Because of the conversion algorithm the files size increases. At the same time, the files have a better quality.

The names of output-files can not be longer than 255 characters.

The device has to be recognized by Windows as a removable disk.

Tunebite  ascertains the CPU performance when installing. A weak CPU performace is not unfavorable for successful videorecording. The detection of the CPU capacity by Tunebite at installation can be improved by deactivating firewalls and antiviruses before installation. Advanced Users can allocate more CPU resources if needed.

Most likely, the system performance for Videos is too low. Go to 'Options> Video> Video size' and select 'Optimized for mobile devices'. Thus, the video size is scaled down by 50%.

Or maybe Tunebite could not switch off the hardware acceleration, which is neccesary to screen copy the video. Please try to disable all hardware acceleration of your grafic adaptor. You can change the setting over 'Desktop> Properties> Settings> Advanced> Troubleshoot'

In some cases, it is possible that a crash of Windows Explorer occurs during installation. It is best to restart the PC and carry out the installation again. 

Please make sure you use the latest version of Tunebite.

If you still have problems with the latest version of Tunebite, please try the following:

(1) Right-click on the speaker icon in the tray. (Normally that's in the bottom-right corner of the desktop)

(2) Click on "playback devices"

(3) In the list of playback devices, right-click on the active speakers and select "Properties..." from the popup-menu.

(4) Go to the "enhancements" tab and select "disable all enhancements".
The so called "enhancements" some soundcards provide may interfere with Tunebite and cause problems. By switching them off, the sound of the playback is identical to the original. That's generally what you want if you re-record songs with tunebite.
