If the bitrate is too low for the dvd player to handle, I would imagine the movie might
1) not play at all, or
2) play improperly with freezing/skipping/garbled/blocky or async playback.

I always set my encodes to min 300 max 2300 so I'm not sure if I'm using too low a min.

I believe
Kwag chose 300 as the minimum bitrate because it is a value that many players could handle properly. Some players can go lower...some need higher (and some need replacing if they don't handle kvcd properly!
). The only way to tell for sure is to do some sample testing on your player with a problematic clip @ different minimum bitrates until you find the sweet spot for your player (or else look at the dvd-models section of this site and look for comments about your brand/model player...but it's probably always best to rely on your own testing
).

Also can burning too fast or using inferior media cause major block distruction and squeels in the audio particularly with an overburn and in the last few minutes of the mpg.

Sure. Some players just don't like some media brands (and some brands
are much better than others...not to mention the possibility of bad batches occurring). And some players might not like discs that are burned too fast. Personally, I always use Fuji (Taiyo Yuden) cdr's and burn at 8x speed, even though it's rated at 48x speed. Some people will tell you that it's better to record at 48x speed if that is what your burner and media support...some disagree. You'll have to wade through the b.s. to figure out what works best for you and your setup
.
I've found more glitches to occur when I burn at 12x or greater. Many people say they burn at 52x and have no problems...more power to 'em.
One note: if you're overburning, it's possible that
1) the media isn't good enough or doesn't like it, even though the burn completes successfully, or
2) your dvd player might have problems reading so far out towards the outter edge of the disc. I'd also recommend burning at 8x or lower speed when overburning because it's harder for your writer's laser to focus on the extreme outter edge of a disc due to increased wobbling, and this is where the overburning occurs.
