vdp-50s and gsearch...

if one is GSearching on a vdp-50, occasionally it seems to do the following

<search> - <XPlxVideoStill> - <GSwitch>

this probably is the same problem diagnosed earlier... but this is more
common and should be fixed. (ie the Switch needs an artificial delay after in in the driver

(I would be willing to fix this if Dan wants)

Hardware limitation.  I think an error message is returned though.  The
alternative is to have the Sony simply to a reverse play and figure
how long in microseconds the section should be, and stop it at the
appropriate place.  This wouldn't be frame accurate, but might be
acceptable.  Sound good to you?

Dan.

having NO playsegs on a SONY is a BAD idea... it becomes too difficult for
the client application.

the reverse guess sounds cool... I am using it to "view" frame-by-frame
for editting...

I think that the thing to do is build the extra timer into the sony
driver.  The only problem I foresee is dealing with RETURN_NOW
playseg's  To do this thing with the timers will require the program
to hang around in the driver until the segment is done and interupting
is tough.

One possibly good idea is to somehow "program" the sony to play
backwards for a certain amount of time.  I don't know if sony programs
are interuptable.  I'll check tomorrow.

Dan.
