i have a vt8233 southbridge (msi k7t266) and problems with it or it has to
be the harddisk or the video.

hdparam say's 24mb is that oke for recording and playback?

for video i use a asus 7700 delux (nvidia gforce 2 gts + video in/out)
works nice for recording(riva (philips SAA7113H)) and playing(nvtv).

processor = 1333 atlon. no problems here (utilization +/- 55%).

i have verry bad qualty wen watching.
do i need to chaince the motherbord ore something else?

greeting michiel

Well, it seems to be a tough call between the SiS 735, and the KT333 with
the newer VT8235 southbridge.
The 735 can be obtained for a mere $52, while the KT333 on a slightly
stripped-down MSI was found for $65. With such a small difference, the
decision rides upon the PCI issues of the VT8235 Southbridge. The 8233
reportedly had latency problems, so I need to know if this has been fixed in
the 8235.

One user (Chris) uses the 8235+KT400 and has no issues.
Are any KTxxx + VT8235 users having non-smooth operation (i.e.: hanging,
Are there any SiS 7xx users out there?
