Can someone post their capture settings  for the PVR-250
frame size
video quality ?%
audio rate kb/s
file size

I tried changing the settings in the "Default" and "Live TV" profiles 
and the entire system seemed to lock.
I had to run setup again and forget all capture cards. So I'm using the 
default settings
480x480
video quality 100%
audio rate 32000
giving me approximately 3 - 3.4 GB/h

Sorry I can't recall whether it the back or front end terminal window 
reports this info
video 480x480 16000 kb/s
audio 48000 Hz 384 kb/s

This seems to imply that the audio quality can't currently be changed 
since both profiles default to 32000 Hz.  That fine, changing the video 
settings would save more drive space anyway.

I see ghosting on my pvr-250 too.  Not real noticeable to watch, but 
I'm sure its contributing to the large file size.  I'm not using the 
best cables but I saw some other people mention ghosting.  Has anyone 
used their pvr-250 card under Windows in the same setup and NOT seen 
the ghosting.  I can't try it myself since I don't have  Windows.  This 
would indicate its the ivtv driver rather than defective hardware or 
bad cabling.

TIA
