Hi Scott,
Did you resolve this?
If not:
Are you using a recovery catalog?
If so, did you try the recovery with 'nocatalog' as well?
What is your MML? If Veritas, my sympathies.
Symantec keeps finding new and unusual ways to break the MML.
If it is Veritas, try using the 'SEND' command rather than using PARMS with
ALLOCATE CHANNEL.
See above about broken MML.
Degging may help. There are a few methods that I know of to turn on
debugging.
ALLOCATE CHANNEL ... debug 6 trace 6.
There are various levels of 1-6 (maybe higher) for each, but it is not well
documented.
OH/bin/rman ... debug trace "quoted output file name"
And an interesting method courtesy of Tuomas Pystynen, though
it won't work on 8.1.7

RMAN tracing
alter system set service_names = 'TEST, TEST_RMAN' scope=both;
exec dbms_monitor.serv_mod_act_trace_enable(
service_name=>'TEST_RMAN',module_name=> 'backup full datafile',waits=>true);
exec
dbms_monitor.serv_mod_act_trace_enable(service_name=>'TEST_RMAN',module_name=>
'backup incr datafile',waits=>true);
$ rman target=sys/password@test_rman
backup device type 'sbt_tape' tablespace 'TEST';
These may help.
