dnh, all see any holes in it or a way to make it better? I was just going to
throw it an a function and write it out...
Just FYI, here is what I ended up with. I added an intermediate tmp file to 
strip the \r:

#!/bin/bash

## dir test
[[ -d /dat_e/dv/new ]] || { echo "No /dat_e/dv/new, exiting..."; exit 2; }
cd /dat_e/dv/new || { echo "cannot change into /dat_e/dv/new, exiting..."; exit 2; }

## read tape count and set up vars & tmp files
tapect=${1:-$(</dat_e/dv/tapect.txt)}
tmpfn=/tmp/dvtmp.log
tmpapp=/tmp/dvapp.log
:>$tmpfn
:>$tmpapp
first_dt=""
last_dt=""

## fix date format from yyyy.mm.dd to mm/dd/yyyy
fixdfmt() {
   [[ -n $1 ]] || { echo "ERROR: Nothing passed to function 'fixdfmt'"; return 1; }
   year=${1//.*}
   day=${1##*.}
   mo=${1%.*}
   mo=${mo##*.}
   echo "${mo}/${day}/${year}"
   return 0
}

## parse dates from $tmpfn to get start and end dates for tape index
getdates() {
   OLDIFS=$IFS
   IFS=$'\n'
   clipct=1
   for i in $(grep \"d $tmpfn); do
     dt=${i//\"dcrv-}
     dt=${dt//_*}
     [[ $clipct -eq 1 ]] && first_dt=$(fixdfmt $dt)
     ((clipct++))
   done
   last_dt=$(fixdfmt $dt)
   IFS=$OLDIFS
}

## download video with output to tmpfn & rewind tape when done
echo -e "\nCapture Started: $(date '+%b %e %T')\n" | tee -a $tmpfn
dvgrab -rewind -timestamp -autosplit=3600 -format raw dcrv- 2>&1 | tee -a $tmpfn
dvcont rewind

## fix the \r issue
cat $tmpfn | sed 's/^[[:space:]]*\r//' > /tmp/fix.log
cp /tmp/fix.log $tmpfn

## get tape begin and end dates
getdates

## write tape No. and begin & end dates to append file
echo -e "\nTape: $tapect  --  $first_dt - $last_dt\n" >> $tmpapp

## write dir content and capture info to append file and append to tape index, 
update capture log
ls -l >> $tmpapp
cat $tmpfn >> $tmpapp
cat $tmpapp >>/dat_e/dv/tape-idx.txt

cat $tmpfn >> /dat_e/dv/capture.log

## move dv clips to permanent dir and mirror on /dat_f
mv /dat_e/dv/new/* /dat_e/dv/sony
cp -uav /dat_e/dv/{sony,tape-idx.txt} /dat_f/dv/

## update tape counter
tapenext=$tapect
((tapenext+=1))
echo $tapenext >/dat_e/dv/tapect.txt
echo "  Tape count updated to: $tapenext"

exit 0
