ShowMe TV does not recover gracefully from viewing MPEG1 movies which are corrupted. Switching back and forth between two MPEG1 movies when one is corrupted, can cause ShowMe TV to fail.
You cannot switch between CIF and QCIF H.261 streams (i.e. regular resolution, or 356x288 size frames, and low resolution, or 176x144 size frames) on non-Ultra systems.
Sending mail (to the broadcaster or to showmetv-comments@Sun.COM) from within ShowMe TV does not work in Asian languages. You can use the Solaris mail functions instead.
Mixing Asian and ASCII characters in one line of text can confuse the input/output functions in ShowMe TV. In particular, if a user sets up a transmission in which the transmission name and/or the hostname contain Asian characters, then saving/recovering these parameters to/from the .showmetv-programs-<hostname> configuration file might not work correctly.
