DRMBuster is an all-in-one file converter for Windows. Unlike other converters, the application offers both audio and video conversion capabilities. However, DRMBuster's specialty is the conversion of files for playback devices. It supports the most of the know input file formats, but only converts files into a handful of formats for video and audio. For example, you can add a .MP4 file to the interface and it will automatically convert it to DIVX, WMV, etc. If you convert audio, the formats are WAV, MP3, AAC, etc. Now, the application works great converting both single and batches of files. However, I see that you can't add several files and convert some to certain formats and some to other formats. You have to specify the output format in the settings, in advance. That is great for when you need to convert your files to the same format, but not for when you just need to convert files to more than one format. I like that it starts converting files automatically, though. I also like that the complete version ($) allows you to burn files and copy them to mobile devices. Another feature worth mentioning is the performance factor. When you install DRMBuster it will scan your computer and give you a performance rating, meaning how fast your computer can handle the tasks.
