[mythtv-users] PVR250: 480x480 vs 720x480

[Volckaert, Jeff]

Hello Everybody,

Up until a few days ago I had been using 480x480 2500-4000
bitrate for recording and getting 1.3G/hour.  My wife got a
dvd/tv combo last weekend though and it can't play misc
mpgs burned to DVD like my other player.  So I changed the
default res to 720x480 and waited to see my 1.3G files
swell up to 2G or more.  Well, that didn't happen.  I still
get 1.3G/hour.  I thought I must have screwed up the change
and it didn't stick.  Nope, it's recording at 720x480 and I
can make a DVD which plays just fine in the dvd/tv combo.

What gives?  Why is 480x480 and 720x480 producing the same
file size?

Thanks,
Jeff
