internet radio (rtsp) traffic denied via ASA5510 inspection

Dear Expert,

I have a question about a Cisco FW (ASA5510+ with v8.0(3)) setup for client
inside FW to access internet public streaming server. Inspection was configured
to inspect rtsp traffic, but some of the internet radio site connection was
teardown with following message(reassembly limit of 8192 bytes exceeded). Is
there any method to overcome the problem instead of not using the inspection.
P'se help!!! Thank.
