    By the way if that is true there is some other issue creating inconsistent fast-forwarding on high def mpeg-2 channels.

    Except I don't think so because I also experienced the same problems watching Heroes on mpeg-4. I think at least the mavs game against Minnesota the other night on 96 was definitely in Mpeg-4.

    95 is MPEG2
    96 and 97 are MPEG4

    So I read the OP post and was thinking...huh? And I've seen other posts about "not being able to see what's being FFW". I don't get it.

    The network I record most is CBS and the only way to record it in my area is the MPEG4 channel. It is pretty bad at times because the OTA signal is pretty bad. Garbage in/garbage out. Also recorded Fox in MPEG4 during some testing of the CEs.

    And of course I FFW all commercials and come out to the programs just fine. FFW2 or 3, replay once..maybe twice and I'm back watching my show. I don't even notice if the FFW images are pixelized, I mean who cares? I'm just looking for the end of the dang commercials and that's easy enough to tell.

    Am I missing something here?

    I agree with the other basketball fans. I get bored with freethrows, so I like to fastforward x1 during freethrows. On MPEG2, I get to see the shots in fast motion, on MPEG4 the fastforward x1 yields a jerky picture with individual frames being displayed with gaps of many frames between each one that is shown and I usually don't get to see if the freethrow went in or not.

    Well the OP may be overstating it a bit, but I am annoyed by this problem too. On my HR10-250 I can FF and see exactly where I'm at as it moves. On the HR20 there is a randomness factor. Sometimes it takes me 9 or 10 of the short rewinds to get back to the start of the show. I don't think it's my response time :). I'd say I get a really bad FF position about 20% of the time using FF3. If I stop down to FF2 when I think I'm getting close it helps.

    To be fair, I suspect the MPEG4 data stream doesn't lend itself well to sampling frames. The HR10-250 doesn't have to deal with this problem.

    I'd say 2x FF is a completely different thing than 3x. With 2x, I pretty much just need a few replays and I'm back to the beginning of the commercial. But the problem is it's so damn slow.

    But you're saying, that with 3x FF, you only need one or two replays to be back at the beginning of the show? That's amazing. Heck, mine jumps ahead at least 10 seconds every time after I'm doing 3x FF and hit replay to stop it. Does your's not have that jump forward?

    mtnagel,

    I think I see the difference in what you are talking about now. Yes, I agree that the MPEG4 is jumpy. I don't think anything of it - in fact, I think I prefer it that way. It appears that you (along with many others) want the jumpiness to be a bit more smooth. That is perfectly understandable. IIRC, the TiVos had a similar problem in the early days. This was with MPEG2-SD of course and may have been more easily corrected. If the jumpiness goes away, I certainly won't complain, but the current method works for me. In short, I'm saying "Yes, you are right." However, it's not something that I, personally, dwell over.

    Add me to the list of those annoyed with the "randomness" and "jumpiness" of the FF/RW. The jumpiness I could live with if the frame on the screen actually correlated to where I end up in the program. For me it doesn't, it's random as far as I can tell.

    Guess I just never notice it. Once in a while I mess up and have to hit replay 3 or 4 times. Perhaps all those hours playing Doom a decade ago sharpened my reflexes. ;)

    I do use FF2 the most though. So maybe it's a FF3 thing. But when I have used FF3 I haven't noticed anything out of the ordinary that would cause me to be upset with the performance. Maybe I'm just not all that picky. :shrug:

    I wasn't looking for affirmation (thought it's always nice to hear someone say you are right :)). I just couldn't believe some were saying they were having no problem with FFing, when it seems like such a common complaint.

    Next time when FFing at 3x on MPEG4 HD stuff, really pay attention to the frame when you hit play (or replay). Then pause for a second as it jumps ahead. Then hit the replay button twice. For me, that pretty much always gets you to right about the frame I thought I stopped on. So I estimate it's jumping forward about 10-12 secs. Give it a try and let me know if that's the case for you.

    And it does not do this with MPEG2 HD or SD. The frame you stop on is the frame that it ends up on.

    +1 to everything said about disliking the FF.

    I know we can't have the same functionality that we did with TIVO, but at least show me where I am, and stop in the right spot!

    I definitely think playing video games as a kid has sharpened my reflexes too. Something will fall and I'll just reach out and grab it before it hits the ground. Amazes me sometimes :)

    Anyway, like I said, FF2 is much easier to tell where you are and stop pretty close to the beginning of the program (but it's way too slow). And I'm coming from an SD Dirctivo, which was very smooth. Maybe my expectations are too high for an HD box, especially with MPEG4, but from the complaints here, I don't think my expectations are too high.
