Regarding the channel at 575MHz, I haven't done a local frequency scan 
in a while now. I received the channel information from the Taiwan 
Digital Television Committe:
http://www.dtvc.org.tw/html/p2_3.htm
If you can't read chinese the chart translates as the following. Taiwan 
currently has 5 TV companies serving the following areas: northern 
Taiwan (Taipei), Xinzhu area, central Taiwan (Taizhong), southern Taiwan 
(Tainan, Gaoxiong, Pingdong), and eastern Taiwan (Ilan, Hualian, Taidong).
Below is another chart listing the channels for each company. Before 
there was more information such as bandwidth, fec, mod, transmission 
mode, etc. But it seems that only the frequency is now listed.
I have only been able to scan for DVB-T channels in Taipei city at work 
using a Twinhan vp-3020. I welcome anyone else in Taiwan to scan around 
and submit their results.
