Why people waste their time and resources to convert a playable format into a possible-but-not-sure format is still a mystery to me... As Xvid is a privately-developed codec there are very few sources that provide native support (I know none but I do not exclude the possibility). On the other hand, all commercial hardware can play the commercial sources, like MPEG-2/VOB/TS/M2TS or even AVC/MPEG-4/etc... The price of kWh is ~0.30-0.35€. The price of storage is less than 30€/TB for HDD and less than 0.5€/GB for SD cards and/or USB sticks. The average loan is 35€/h. And now it's getting warmer and warmer, so even the excuse of using the CPU at 100% for hours to heat the rooms will fall...
