....straight from wiki:
HD DVD-R / -RW / -RAM

HD DVD-R is the writable disc variant of HD DVD, available with a single-layer capacity of 15 GB or a dual-layer capacity of 30 GB.[63] Write speeds depend on drive speed, with a data rate of 36.55 Mbit/s (4.36 MB/s) and a recording time of 56 minutes for 1× media, and 73 Mbit/s (8.71 MB/s) and a recording time of 28 minutes for 2×.

The Toshiba SD-L902A for notebooks was one of the first available HD DVD writers, although it was not meant for retail.[64][65] Burning HD DVD (including Dual Layer) with a 1× write speed, it could also burn DVDs and CDs. In a test of the SD-L902A by C't computer magazine with Verbatim discs, the written HD DVD-Rs suffered from high noise levels[66]; as a result, the written discs could not be recognized by the external HD DVD drive of the Xbox 360, though they could be read back by the SD-L902A.[67]

HD DVD-RW is the rewritable disc variant of HD DVD with equal storage capacity to an HD DVD-R. The primary advantage of HD DVD-RW over HD DVD-R is the ability to erase and rewrite to an HD DVD-RW disc, up to about 1,000 times before needing replacement, making them comparable with the CD-RW and DVD-RW standards. This is also of benefit if there are writing errors when recording data, as the disc is not ruined and can still store data by erasing the faulty data.

HD DVD-RAM was the proposed successor to DVD-RAM for random access on optical media using phase-change principals. It would hold 20 gigabytes per layer instead of 15 gigabytes for HD DVD-R, due to differences in recording methods used, yielding a higher density disc. The future of this format is uncertain, given Toshiba's announcement of withdrawal of support for the HD DVD format as a whole.

DVD / HD DVD hybrid discs

There are two types of hybrid formats which contain standard DVD-Video format video for playback in regular DVD players, and HD DVD video for playback in high definition on HD DVD players. The Combo disc is a dual sided disc with one side DVD and the other HD DVD, each of which can have up to two layers. The Twin disc is a single sided disc that can have up to three layers, with up to two layers dedicated to either DVD or HD DVD.[68] These hybrid discs make retail marketing and shelf space management easier. Another advantage is hardware cross-compatibility. The average consumer doesn't have to worry about whether or not they can play a hybrid DVD: any standard home DVD player can access the DVD-encoded content and any HD DVD player can access both the DVD- and HD DVD-encoded content.

HD DVD / Blu-ray hybrid discs

Warner Bros. officially announced Total Hi Def (THD or Total HD) at CES 2007. THD hybrid discs were to support both HD DVD and Blu-ray, with HD DVD on one side (up to two layers) and Blu-ray on the other side (up to two layers). However, in November 2007 Warner Bros. cancelled THD development.[69]

3× DVD

The HD DVD format also applies to current red laser DVDs; this type of disc is called "3× DVD", as it is capable of three times the bandwidth of regular DVD-Video.

3× DVDs are physically identical to normal DVDs. Although 3× DVDs provide the same high definition content, their playback time is less. For example, an 8.5 GB DVD can hold about 85 minutes of 1080p video encoded with VC-1 or AVC at an average bitrate of 13 Mbit/s, suitable for short subjects (training films, home movies, very short feature films), but unsuitable for most feature film-length content.

It is technically possible for consumers to create HD DVD compatible discs using low cost DVD-R or DVD+R media. At least one such guide exists.[70] The 3× DVD is comparable to Blu-ray BD5 and BD9 formats.

HD REC

HD Rec is an extension of the HD DVD format for storing HD content on regular red laser DVDs using H.264/MPEG-4 AVC compression.[71] It was approved by the DVD Forum on September 12, 2007[72] It is comparable to Blu-ray's AVCREC.

blu-ray info:

Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage media format. Its main uses are high-definition video and data storage. The disc has the same dimensions as a standard DVD or CD.

The name Blu-ray Disc is derived from the blue laser (violet coloured) used to read and write this type of disc. Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A dual layer Blu-ray Disc can store 50 GB, almost six times the capacity of a double-dual layer DVD (or more than 10 times if single-layer).

During the high definition optical disc format war, Blu-ray Disc competed with the HD DVD format. On February 19, 2008, Toshiba — the main company supporting HD DVD — announced it would no longer develop, manufacture, and market HD DVD players and recorders,[2] leading almost all other HD DVD companies to follow suit, effectively ending the format war.

Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing consumer electronics, computer hardware, and motion picture production. As of August 27, 2008 more than 780 Blu-ray Disc titles have been released in the United States and more than 480 Blu-ray Disc titles have been released in Japan.[3][4] By the end of this year, there will be a total of 1192 Blu-ray Discs released.[5]

The DVD Forum (which was chaired by Toshiba) was deeply split over whether to develop the more expensive blue laser technology or not. In March 2002, the forum voted to approve a proposal endorsed by Warner Bros. and other motion picture studios that involved compressing HD content onto dual-layer DVD-9 discs.[24][25] In spite of this decision, however, the DVD Forum's Steering Committee announced in April that it was pursuing its own blue-laser high-definition solution. In August, Toshiba and NEC announced their competing standard Advanced Optical Disc.[26] It was finally adopted by the DVD Forum and renamed HD DVD the next year,[27] after being voted down twice by Blu-ray Disc Association members, prompting the U.S. Department of Justice to make preliminary investigations into the situation.[28][29]

HD DVD had a head start in the high definition video market and Blu-ray Disc sales were slow at first. The first Blu-ray Disc player was perceived as expensive and buggy, and there were few titles available.[30] This changed when PlayStation 3 launched, since every PS3 unit also functioned as a Blu-ray Disc player. At CES 2007 Warner proposed Total Hi Def which was a hybrid disc containing Blu-ray on one side and HD DVD on the other but it was never released. By January 2007, Blu-ray discs had outsold HD DVDs,[31] and during the first three quarters of 2007, BD outsold HD DVDs by about two to one. Finally, by February 2008, Toshiba announced it was pulling its support for the HD DVD format, leaving Blu-ray as the victor in the video wars.[32]

Some analysts believe that Sony's PlayStation 3 video game console played an important role in the format war, believing it acted as a catalyst for Blu-ray Disc, as the PlayStation 3 used a Blu-ray Disc drive as its primary information storage medium.[33] They also credited Sony's more thorough and influential marketing campaign.[34] More recently Twentieth Century Fox have cited Blu-ray Disc's adoption of the BD+ anti-copying system as the reason they supported Blu-ray Disc over HD DVD.[35]
