ImgBurn

ImgBurn is a lightweight CD / DVD / HD DVD / Blu-ray burning application that everyone should have in their toolkit!

ImgBurn supports a wide range of image file formats - including BIN, CCD, CDI, CUE, DI, DVD, GI, IMG, ISO, MDS, NRG and PDI.

It can burn Audio CD's from any file type supported via DirectShow / ACM - including AAC, APE, FLAC, M4A, MP3, MP4, MPC, OGG, PCM, WAV, WMA and WV.

You can use it to build DVD Video discs (from a VIDEO_TS folder), HD DVD Video discs (from a HVDVD_TS folder) and Blu-ray Video discs (from a BDAV / BDMV folder) with ease.

It supports Unicode folder/file names, so you shouldn't run in to any problems if you're using an international character set.

ImgBurn supports all the Microsoft Windows OS's - Windows 95, Windows 98, Windows Me, Windows NT4, Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows 2008 and Windows 7 (including all the 64-bit versions). If you use Wine, it should also run on Linux and other x86-based Unixes.

It's a very flexible application with several advanced features that are often lacking in other tools, especially when it comes to burning DVD Video discs. It supports all the latest drives without the need for updates (including booktype / bitsetting / advanced settings on many of the major ones - i.e. BenQ, LiteOn, LG, NEC, Plextor, Samsung, Sony).

There is an image queue system for when you're burning several images (which you can automatically share between multiple drives if you have more than one) and an easy-to-use layer break selection screen for double layer DVD Video jobs. The Automatic Write Speed feature allows you store your favourite burn speed settings on a per 'Media ID' basis, right down to a drive by drive level. Data captured during the burn (write speed, buffer levels etc) can be displayed / analysed using DVDInfoPro.

Whilst ImgBurn is designed to work perfectly straight out of the box, advanced users will appreciate just how configurable it is.

Oh and let's not forget the best thing about it.... it's 100% FREE.

GOM player

GOM Media Player Features
Codec Finder

GOM Media Player comes equipped with all of the most popular video codecs (XviD, DivX, FLV1, OGG, MP4, H263 and more) by default, so downloading and installing extras is rarely necessary. For those videos that do require a separate codec, GOM Media Player will find one and direct you to a place where you can download an open source version. That way, you won't get stuck with unnecessary codecs on your system.
Play Broken AVI Files

AVI files can't be played if the index is broken, or if the file isn't completely downloaded. This is because the index is located at the end of the file. GOM Media Player's advanced technology enables users to view files with broken indexes or that are still being downloaded.
Powerful Subtitle Support

GOM Media Player supports SMI, SRT, RT, and SUB(with IDX) subtitle formats. You can specify margin, location, size, resolution, font and others. You can also enable shadow, view ASF files with subtitle, karaoke subtitle mode. You can even synchronize subtitle and video if there's any mismatch.
Convenient Playlist

It's easy to create and edit your own multimedia playlist with GOM Media Player. If there are multiple videos with similar names in a given directory (i.e. "Sample Episode 1", "Sample Episode 2", etc) they will all be automatically added to your playlist when you choose to playback one of them. Furthermore, because GOM Media Player uses a playlist format that is similar to M3U, PLS, and ASX, playlists that are saved in any of those formats can be opened and edited as well.
Support Different Media Types

GOM Media Player can play all the most popular video formats by default, including AVI, MP4, MKV, FLV, WMV, and more.
Screen Capture

Screen capture allows you to take a screenshot of your video directly from GOM Media Player. Using the Burst Capture feature, you can take continuous screenshots up to 999 shots.
Advanced Features

There are an extensive number of advanced features included in GOM Media Player. You can customize brightness, contrast and saturation, sharpen and add noise to your video, adjust audio output using the audio equalizer, repeat a section of your video with our A-B Repeat feature, make use of loads of keyboard shortcuts, and much more!
