VDSL or Cable Modems: Which are available in China?

Hi, i'm getting ready to move to Beijing.  I am wondering what type of home internet access cpodders are using in Beijing or Shanghai. I've casually done internet searches, and unfortunately, it appears that VDSL is the (emerging?) dominant method for connecting to the internet.  I had a bad experience with DSL in Lanzhou in that big powerpoint files (like 5MB in size) wouldn't download, and Sametime Connect wouldn't work.  If the only available method is VDSL or DSL, then I guess that's what I'll have to use, but then I wonder if cpodders are having success downloading large ppts or large files in general. Thanks for your thoughts.
