[robocup-msrs] Problem while using the SimulatedRobuDOG service

[Zemat]

Ok, I checked and the problem arose because I mistakenly installed again the
old package over the new one.

I redownloaded the package and installed it, which fixed the problem (frames
are now 320x240). Thanks for the help!

Regards,
Juan Bernardo Tamez.
