Hello there Dan,
Bad news on your problem. The synch problem you mention is a well-known
problem of the Hauppauge card and basically, of many internal
tuner/digitizing cards. :mad:
What happen iis that the card and HDD can not keep up with the data
flow coming in. as a result you periodically lose frames during
aquisition. You do not notice it at first as the file you aquire is in
synch (the frame drop being synchronous to the audio track) The problem
when you recompile the file is that tue compilation takes the frames and
basically puts them one after the other filling in the missing frames
with the ones afterwards etc etc etc. in the end you wind up with up to
a full minute out of sync on a single hour movie. :mad:
I own a Wint TV PVR PCI and a PVR 250. I used them to record my tv
shows and series. It worked fine until I decided to start burning DVDs
( I had 6 120Gb HDD full at the time) You can guess the result ! It
took me 20 dvds before I found the info on a couple of sites. :mad:
:mad:
Now I use a Dazzle DVC 150 to record my movies. :) :thumb: I have
scratched most of my recent recordings and I am using two PCs to
re-record my older (almost collector) recordings. To save them I ply
them full screen on the first PC with the TV and audio outputs plugged
into the Dazzle DVC 150 input. I still lose a bit of quality but it's
worth it. :D
Now the PB with the Dazzle is the lack of programming as with the
Hauppauge but at least I get to burn my dvd without Problem. I am
honestly considering buying a second one to be able to record two
programs simultaneously ( I have 4 PCs :rolleyes: )
Oh, another piece of advice, to minimize the out-of-synch PB when you
digitize whith the hauppauge:
1. use 2 HDD and don't aquire to the system drive
2. defragment the drive before acquisition
3. Always have at least 512 Mb *_FREE__*ram
4. a Pc below 2Ghz has no chances. :eek:
