I went ahead and tried doing a 'mplayer /dev/video0' and I get a 
beautiful picture and sound, for about 4 or 5 seconds.
Then it freezes up.


Here is some hardware info (PVR250 of course):
rocessor is an AMD Athlon Thunderbird 1Ghz Socket A chip.

Motheboard is ASUS A7V (with latest BIOS)

Video Card is a Palit Microsystems Daytona GeForce4 MX 440SE AGE 64MB card
I have it set up for X to have two displays. The first uses VGA out to 
my monitor with a resolution of 1152x768 (24bit)
My second 'display' I use the cards RCA out and it goes to my 
television. I have it set to a resolution of 640x480 (24bit)

Sound card is a Creative Labs Soundblaster 16 PCI card

I have 512MB of RAM

I have two hard drives. On my primary IDE:
Primary is an IBM-DTLA-307060 DeskStar 60GB
Secondary is an Hitachi/IBM 120GB 7200RPM Deskstar 120GXP

On my secondary controller I have two CD-ROM drives:
Primary is a CREATIVE CD-RW RW8438E
and secondary is a generic 50x ATAPI CD-ROM drive.

My hard drive controller is "VIA vt82c686a (rev 22) IDE UDMA66 
controller on pci00:04.1"

I downloaded IVTV CVS on May 31st 2003.
Initially MythTV CVS I had downloaded and installed on the same day.
But I wasn't able to change channels with it.
So I waited a bit. Then I just downloaded new CVS and recompilied on 
June 6th 2003.
The new version allows me to change channels fine, but I have to do it 
quick in order for it not to lock up. A few seconds of playing and boom. 
Freeze.
So IVTV is 5/31/2003 and MythTV (and MythVideo) is 6/6/2003


Since mplayer freezes up, it might not be a mythtv issue. It's probably 
a ivtv or bttv bug?
