唉…這就是沒開BD討論區的缺憾…
1.先弄清楚什麼是AVCHD吧
2.雖然目前硬碟很便宜，但是不方便交流，（仁兄，借個5片來看看…不巧，這5片都放在5個不同的硬碟，你會同時出借5顆硬碟嗎？就算你會，歸還時發現資料都不見了，哭的人是誰?）
3.一旦要備份到達幾百片時，就會知道痛苦（我還有很多沒看耶，到底要殺哪些片）
4.想想當年DVD SHRINK出現時造成的流行吧
5.現在有人玩BD5和BD9，好熬過BD片和BD燒錄器價高的時代，AVCHD的BD9，分辨率可達1920X1080，音效為640K的AC3或降轉的1536K的DTS，BD5則為1280X720，音效多為AC3。

Doesn't work on:
Sharp BD-HP20(U)

Bluray releases are only guarunteed to play on PC.
Most 720p will play on popcorn hour/tvix. Some 1080p
will play on popcorn hour/tvix. Some 720p will play
on PS3 with some manipulation and AC3 only. Very few
1080p will play on PS3. All are incapable of playing
on bluray standalones.

games that dont play on pc = nuke
apps that dont work on pc = nuke
consoles that dont play = nuke
dvdr that doesnt play on standalone = nuke
xvid that doesnt play on standalone = nuke
svcd that doesnt play on standalone = nuke
bluray that doesnt play on standalone = WAKE UP PEOPLE !!!
