Hi,

I'm not sure if this is the same problem you are referring to, but I 
bought an HVR-1950, and it __almost__ works.

Currently I'm just using the analog NTSC composite input and stereo 
analog audio input, which are attached to my satellite receiver from its 
analog outputs.

Like i said, it _almost_ works, but appears that the box will not shift 
from PAL standard to NTSC standard.

http://ponzo.net/newshawk/example.mpg is 52 megs of captured video...

I've attached a sample frame, and it looks to me like it's trying to use 
PAL instead of NTSC.  In fact, even trying to change it with the /sys 
filesystem to NTSC-M yields the same result (but the driver reports it 
is in NTSC-M mode).

Would love to get this working, and would even drop-ship one of these 
units to you, Mike, if you don't have one yet.

Thanks! :)
