Just though i might say... ( Put in my 2 cents lol )
I play all my files on my TV from computer via a external hard drive media player ( Supports ALOT of different file extensions, EG: MPEG1/2/4, AVI (MPEG4, Xvid, AVC),DivX3.X-5.X, VOB, DAT, ASF, VCD, DVD )
.mp4 files are very small ( but bad in quality lol , abit of give and take
You can pick these up @ around $220 AUD at ebay... ( i paid 240 for 1TB / 1,000GB , and not one complaint on any dollar )
All your data on one single volume , no need for cd / dvd these days...
If you have a DVD Player , you will more then likely be able to use these external media players ( just use's red , yellow and white plug )
Best of luck !
