Sounds like you've either configured the PVR-150 to use the Tuner or
Television or whatever it's called input rather than S-Video or Composite
or
you have a broken channel change script in use by the PVR-150.
For either of these, see the last paragraph, below.

IMHO, rather than getting a new card, you'd be better off just getting
one or more A/V cable sets to allow you to use the 2nd encoder on your
PVR-500s.

(unless you can get new PVR-150's or 500's for cheaper).

Only through defining a new Video Source in MythTV. However, as you
said, there is absolutely no reason that the PVR-150 would care what the
channel number is when using Composite or S-Video input, so the breakage
is somewhere in your MythTV configuration.
If you want to set up, again, using a clean slate, go into mythtv-setup
and "Delete all capture cards" (not "Delete all capture cards on
<hostname>"), then re-create capture cards, re-connect inputs (and set
up channel change script command lines), then enjoy. You won't lose
your Video Sources or channels in the process, so it should only take a
few minutes to do. And, if you do a database backup (
http://www.mythtv.org/wiki/Database_Backup_and_Restore ), first, you
have nothing to lose--you can always restore the backup and be right
back where you were.
