Can't eject DVD

I have a Dell laptop running Windows XP. Sometimes I can't eject the DVD.
The easiest way to solve this problem is by disabling and enabling the DVD-ROM drive from the device manager.

Just right click on My Computer, select Hardware, find the DVD-ROM drive, select disable, then enable. That's all.

No video on TPG's IPTV

I could hear the audio, but no video on TPG's IPTV. It was working properly a few weeks ago.

How did I fix it?
I uninstalled the existing VLC media player(0.8.6), then installed the newer version (1.1.5). Don't forget to check the 'Firefox' option during the installation.
