setting capture settings for pvr-250

ivtv mentions it drive for the pvr-250 now supports 4 or 5 resolutions
has this made it into mythtv cvs? I have cvs as of Friday night for
both ivtv and mythtv.

I reason I ask is I now have mythtv running on a Athlon XP 2500 and
when I change the capture settings the entire system locks up. Has
anyone seen this and found a solution.

I have mythbackend starting at boot up and the system immediately locks
if a recording is scheduled at the same time. Rather inconvenient and
aggravating.

I have tried 720x480 at 75% and 640x480 at 60% both lock up the system
completely. The only config that presently works is 480x480 at 100%.
mythtv reports is using 480x480 at 16000 Kb/ video and 48000 Hz audio
at 384Kb/s. Nice picture on the monitor but I would rather have a
slightly smaller file. Currently about 3.3 GB/hour! This means I can
only get 33 hours on my 120 GB drive. A little on the low side.

The lock up puzzles me because mythfrontend and mythbackend are only
using 16 % combined on the XP 2500.

Suggestions please.

TIA

There's no custom resolutions on a per-card basis right now. If
you're willing to hack around, then you could do something like I
did, which is to add two profiles called "PVR-250 Recording" and
"PVR-250 Live" and set them to 720x480. I then changed the Default
and Live profiles back to 480x480 for my BT8x8 cards. See the mc.sql
file for how to add a profile, and then configure your custom
profiles in mythfrontend. Add the next bit of code and change the
hostname for whatever is appropriate for your setup.

NOTE: You're on your own if it doesn't work or you mess up your
system.

I made my original capture changes in "Live TV" and "Default" profiles.
I only have the pvr-250, so won't those profiles work with this card
without the code changes suggested? The changes suggested were for a
system with 2 different types of capture cards, correct?
