RVLC and data partitioning are only useful for transmissions with bit errors.
In the usual internet environment (IP/UDP/RTP) packets with errors are
discarded (as you said) and not delivered to the client application. Only the
video packet resync markers are useful to divide a video access unit into
several rtp packets that are decodable separately.
In closed ip-networks over radio links with a moderate bit error rate it may
be useful to deliver error prone packets utilizing the UDP-lite internet
draft <draft-ietf-tsvwg-udp-lite-01.txt> instead of discaring all packets
with errors completely. In this environment the use of data partitioning and
RVLC makes sense.
