我不同步的問題還是在，長時間很難同步~
我目前是設定
winxp buffer & master stream -> audio
MP3 256kbit 44kHz
DIVX 5.02 98%
因為平常都在錄MTV台
只要超過二小時，就會開始不同步~
不同步和設定似乎無關
只好用FLY 2000 TV 的分段功能，大概90分鐘一段
再以VD來合
但是常會因流量的不同而無法合併(有時可，有時不可)
有沒有人和我有一樣的困擾??有沒有解決的方法?

等等新的驅動還有下一版改進吧.... 原作者在Q&A裡有提到
FLY 2000 TV - Advices of video capture
Unfortunately, WDM drivers for Philips saa713x chips and built on LifeView LR138 reference-design, yet are not lead up to perfection. In them till now there are some problems interfering to the users of cards to use of possibility of the chip completely. I shall list main problems:
At capture of a video, always try to use the format YUY2 for minimum load at the system and getting best quality image, as the format YUY2 does not sustain a redundant information. But in formats which are differ from RGB - for example in YUY2, UYVY, YV12, that is to say in YUV- component, the driver saa713x informs about negative value of vertical size, for example 720x-576. If biHeight is positive, the bitmap is a bottom-up DIB and its origin is the lower-left corner. If biHeight is negative, the bitmap is a top-down DIB and its origin is the upper-left corner. Many DirectShow filters and codecs, and also, filter Microsoft AVI Mux do not understand (-) biHeight. At build DirectShow graph manager with such filters and attempt capture in anyone YUV- the component format - several filters cause adding in the graph the AVI Decompressor filter, distorting capture formats, several filters causes crash Windows. LifeView Driver 20.50 and higher, solved this problem.
When switching channel or videoinput, WDM driver confuse Comb filter parameters, that sometimes give grid over image in SECAM format, or blur (the shift) color in PAL format.
WDM driver supports a maximum size of a frame only 720x576. Mode 768x576 made via interpolation from 720x576. So better capture in 704x576 or 720x576.
WDM driver of tuner control not support TV frequency below 55 MHz and above 800 MHz. It is necessary to do switch channels through low-level COM interface.
WDM driver not support FM Radio mode. It is necessary to do work with FM radio through low-level interface.
About codecs...
As far as possible, do not make capture in AVI, with compression of audio on real-time.
It threatens with desynchronize of video and audio streams, or at some audiocodecs can cause sudden break of record. Use the hardware audio format - PCM.
