LinuxQuestions.org - Is ubuntu worh it?

I've been trying to sort out the networking and play back of DVDs.
I have found this an impossible mission so god knows what I'm going to do when i download ableton live.
Anyway, at every step I find it impossible to run programs. Bzip2-1.0.5, for example, doesn't have any file in it that I double click to make it install.
When I do find a file like that, in the following example, SM Player, and I click it, I get a message that reads thus;
An error occured while loading the archive.

Comand Line Output:

Archive: /home/owner/Desktop/SMPlayer/smplayer.exe
Zip file size: 3222528 bytes, number of entries: 35264
warning [/home/owner/Desktop/SMPlayer/smplayer.exe] end-of-central-directory record claims this
is disk 29160 but that central directory starts on disk 65510; this is a
contradiction. Attempting to process anyway.
error [/home/owner/Desktop/SMPlayer/smplayer.exe]: missing 2875685792 bytes in zip file
(attempting process anyway)
error [/home/owner/Desktop/SMPlayer/smplayer.exe]attempt to seek before beggining of zipfile
(please check that you have transferref or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

I keep ending up going around in circles. How am I suppose to compile the Unzip properly when there isn't a file to set up bzip? And if there was I'd surely get a message like above.
I purchased this computer primarily for home music production, I've heard that Linux/ubuntu may not be best for home creative purposes.
Should I just give up and boot up XP. It'd be a shame because I hate Microsoft, as a company and their software (ubuntu doesn't do that gay 'dun dun dun dun' thing when it starts up and shutsdown, just one of the many advantages I've discovered in my short and frustrating time with ubuntu) and I would like to support the Linux philosophy but I'm not sure if this is worth the time I'm having to spend.
